#12876 new bug

network performance degrades over time

Description

I'm currently using my machine as a build slave to test the package build infrastructure. This means rather long uptimes (ideally several days).

Haiku seems to be quite stable, however, the network access becomes slower and slower over time, up to a point where everything seems to timeout and I have to reboot the computer.

I'm not sure what the problem is or how to investigate.

This is a wireless connection which makes it difficult to spy the traffic on the wire.

device Network controller [2|80|0]
  vendor 8086: Intel Corporation
  device 008a: Centrino Wireless-N 1030 [Rainbow Peak]

Wifi-N is disabled at boot using ifconfig, as it isn't working with this device.

I am also experiencing a network slowdown over a period of time, much as you have described. In my case, I am using a wired connection and must reset the modem/router to restore the performance.

Is this still reproducible? At least I could imagine that mmlr's DMA alignment fixes could have an impact on such issues.

Yes, I still run into this problem. I have some more precise information as I continue to watch for it. It seems that what becomes slow is opening of new connections. I suspect some problem in TCP handshake or similar. Eventually, it is so slow that it times out, and no connection can be opened. But even in that state, where I can't download anything with wget, I can still use Vision as long as its sockets to IRC servers stay open.

I experience the same problems with rtl81xx on bare metal.

Yesterday I started rsync transer from macOS -> Haiku, copying ~30.000 files. I left it unattended, and when I wanted to issue another git clone from a terminal, I got only ~ 30 KiB/s, which went up to ~600 KiB/s after a reboot.

I don't know what could be done to debug this though - I'm a Haiku newbie :-)

Hmm, I wonder if this is related to #11836?
