Why Is Batocera So Slow to Download?

Usually a server, connection, or download method issue — here’s how to speed it up

---

Downloading Batocera Linux — whether the main image file or the scraper content, game thumbnails, or system updates — taking much longer than expected has specific, addressable causes.

The download itself is rarely the permanent problem.

It’s almost always a server load issue, a mirror selection problem, or something about how the download is being handled.

Here’s every cause and how to improve download speed.

Understand What You’re Downloading

Batocera has several distinct download types, each with different size and speed characteristics:

The main Batocera image file — the bootable Linux image you flash to a USB drive or SD card. Typically 1 to 4GB or more depending on the version and architecture (x86_64, Raspberry Pi, Odroid, etc.). This is a single large file download.

In-system updates — Batocera’s built-in update system downloads updates from Batocera’s own servers. Size varies by version jump.

Scraper content — game metadata, box art, and media files downloaded by the built-in scraper (ScreenScraper, TheGamesDB). This isn’t a single download but potentially thousands of small files.

ROM downloads — if you’re downloading ROMs from any source (though this is a separate topic from Batocera itself).

Identifying which type is slow points to the right fix.

Check Your Internet Connection First

Before assuming it’s Batocera’s servers, confirm your connection is performing normally for other large downloads.

Run a speed test at fast.com and compare the result to what you’re getting from Batocera. If your speed test shows normal speeds but Batocera’s download is slow, the bottleneck is the download source rather than your connection. If speed tests are also slow, fix the local connection first.

The Batocera Servers May Be Under Load

Batocera’s download infrastructure is smaller than commercial software providers, and during peak periods — after a major new version release, on evenings and weekends, or during community events — the official servers get congested and speeds drop significantly for everyone simultaneously.

Check the Batocera forums (batocera.org/forum) or the Batocera Discord to see whether others are reporting slow downloads at the same time. If it’s a server-side load issue, waiting and downloading during off-peak hours (overnight, early morning) typically produces significantly better speeds than downloading during peak evening hours.

---

Use a Download Manager

Downloading a large file like the Batocera image through a standard browser is one of the slower methods available — browsers don’t typically use multiple connections to the same server or resume interrupted downloads efficiently.

A dedicated download manager handles large files more effectively:

JDownloader (free, Windows/Mac/Linux) — automatically uses multiple connections and handles resume after interruption.

Free Download Manager (free, Windows/Mac) — similar multi-connection support.

aria2 (command line, all platforms) — powerful multi-connection downloader, particularly useful on Linux.

Using a download manager with multiple parallel connections to the same server often doubles or triples effective download speed from the same source compared to a browser download.

---

Try a Different Mirror

Batocera may offer mirror servers in different geographic locations — connecting to a mirror closer to you geographically typically produces significantly better download speeds than downloading from a distant primary server.

Check the Batocera download page (batocera.org/download) for any listed mirror options. If mirrors are listed for different regions, select the one geographically closest to your location rather than the default.

Also check whether the Batocera community has shared alternative download sources — the official forum and Discord frequently have members who have created mirrors or torrents of current releases that may be faster than the primary server.

---

Use BitTorrent If a Torrent Is Available

If a torrent link is available for the Batocera version you need, this is often the fastest download method when many people are seeding — BitTorrent distributes the download load across multiple peers rather than relying on a single server.

Check the Batocera download page and community forums for any .torrent files or magnet links for your target version. Use a torrent client like qBittorrent (free, open source) to download — if the torrent has many seeders, speeds are typically much higher than direct server downloads.

---

Check Your DNS Settings

Slow DNS resolution can affect download speeds by adding latency to each connection request — particularly relevant when the download involves many small files (scraper content) rather than a single large image.

Switch to a faster DNS server. Go to your network adapter settings and set DNS to:

Cloudflare: 1.1.1.1 and 1.0.0.1
Google: 8.8.8.8 and 8.8.4.4

Flush your DNS cache after changing: open Command Prompt and run ipconfig /flushdns (Windows) or sudo dscacheutil -flushcache (Mac).

For In-System Updates — Check Network Configuration in Batocera

If the slow download is happening inside Batocera itself — the system update or scraper — the network configuration within Batocera may need attention.

Check Batocera’s network settings:

In Batocera’s main menu, go to System Settings → Network Settings and confirm the correct network interface is configured and connected. A misconfigured network that’s falling back to a slower connection type produces slow update speeds.

Use a wired connection if possible:

If your Batocera device is connecting over Wi-Fi, switching to a wired ethernet connection significantly improves both speed and stability for large updates. This is particularly important on Raspberry Pi builds where Wi-Fi performance is more limited than on x86 hardware.

---

For Scraper Downloads — Adjust Scraper Settings

The built-in scraper downloading thousands of individual images and metadata files can feel extremely slow because of the sheer number of individual requests rather than bandwidth limitations — each file requires a separate connection to the scraper service.

In Batocera’s scraper settings:

Reduce the number of media types being downloaded — if you’re scraping box art, videos, fan art, and marquees simultaneously, limiting to just the media types you actually use (typically box art and maybe video snaps) dramatically reduces the total number of files and overall scrape time.

Use ScreenScraper with an account:

ScreenScraper limits download speeds for anonymous users more than for registered accounts. Creating a free account at screenscraper.fr and entering your credentials in Batocera’s scraper settings often dramatically increases scraping speed.

Scrape during off-peak hours:

ScreenScraper and similar services get congested during peak hours. Scraping overnight or early morning produces significantly faster results than during evening peak times.

---

Check for ISP Throttling

Some ISPs throttle specific types of traffic — large file downloads, Linux image files, or torrents — at certain times of day. If your speed test shows normal speeds but downloads from Batocera’s servers are consistently slow regardless of time of day, ISP traffic shaping may be a factor.

Test by downloading the same file using a VPN — if speeds improve significantly with a VPN active, ISP throttling of that specific traffic type is likely. Note that VPNs can also sometimes reduce speeds if the VPN server itself is congested, so test a few different server locations.

---

Try the Download on a Different Device or Network

To confirm whether the slowdown is specific to your device or network, try downloading Batocera on a different device or from a different network (a mobile hotspot, for example).

If the download is significantly faster on a different network, your home network or ISP has an issue specifically affecting downloads from Batocera’s servers. If it’s equally slow on multiple networks, the Batocera server load is the cause rather than your local setup.

---

Check Available Storage Speed

If the download appears to be downloading at reasonable speeds but writing to the destination is slow — a USB drive, SD card, or slow external storage — the bottleneck is the destination rather than the download itself.

Writing a Batocera image to a slow USB 2.0 drive or a slow SD card is significantly slower than writing to a fast USB 3.0 drive or a quality SD card. Check the write speed specification of your destination media — budget SD cards in particular can have very low sequential write speeds (10 to 20 MB/s) that make even a fast download appear slow because the bottleneck is writing the data to the card.

Use a quality USB 3.0 drive or a fast SD card (UHS-I or UHS-II rated) for significantly better write performance during the flashing process.

A Quick Checklist

Work through these based on what’s slow:

Main image download is slow:

• Check speed test to confirm connection is performing normally
• Check Batocera forums or Discord for reported server issues
• Try downloading at off-peak hours
• Use a download manager like JDownloader or Free Download Manager
• Check for a torrent alternative to direct download
• Try a different mirror if available

In-system Batocera update is slow:

• Switch to wired ethernet if on Wi-Fi
• Check Batocera network settings for correct configuration
• Try the update during off-peak hours

Scraper is slow:

• Create a free ScreenScraper account and add credentials in Batocera
• Reduce scraped media types to only what you need
• Scrape during off-peak hours

All downloads slow:

• Switch DNS to Cloudflare (1.1.1.1) or Google (8.8.8.8)
• Test on a different network to isolate home network vs server issue
• Check for ISP throttling with a VPN test

The Bottom Line

Batocera downloads slowly most often because its community-maintained servers handle less traffic than commercial providers, and peak-time congestion causes significant speed drops for everyone simultaneously.

Downloading during off-peak hours — overnight or early morning — and using a proper download manager rather than a browser handle most cases without any technical fixes needed.

For scraper slowness specifically, creating a free ScreenScraper account is the single most impactful fix — anonymous scraping is rate-limited in ways that registered accounts aren’t, and the difference in speed is often dramatic.

Batocera’s servers are community infrastructure, not enterprise CDNs — download off-peak, use a download manager, and the speeds come up to something reasonable.
