Custom Chunk Size

Tune chunk size to match your network and server profile. Smaller chunks help unstable connections recover quickly; larger chunks reduce HTTP overhead on fast networks.

What you should see: 2 MB chunks instead of the default. Pick a file over 2 MB and the network panel shows several numbered chunk POSTs plus one completion call; smaller files still take the single-request path.

Tip: Start around 1 MB to 5 MB. Raise it for fast LAN or intranet uploads, lower it when users are on mobile or unreliable links.
