whit game server i have 280 ping ,i need mudfish to reduce the ping ,but whit download server i have just 17 ping .
so can i just use mudfish only on game server, but no on download server? (android)

If you’re using the per-app mode of mudfish android app, unfortunately no way to avoid because it’s working based on the app-id…

So if you want to avoid this issue, I think you should play it with android emulator and make Create Custom Item for this purpose.
