Description Max Prohorov 2011-05-29 17:49:58 UTC

With 'utp' useflag it is (probably) required to increase net.core.wmem_max/rmem_max in /etc/sysctl.conf

As it is got mentioned in transmission.log:
...

18283 May 29 21:03:03 localhost transmission-daemon[18533]: UDP Please add the line "net.core.rmem_max = 4194304" to /etc/sysctl.conf (tr-udp.c:80)
18284 May 29 21:03:03 localhost transmission-daemon[18533]: UDP Failed to set send buffer: requested 1048576, got 262142 (tr-udp.c:86)
