Hello.
I have found out that the slow-down issue with many sockets is a memory problem now. Not that I do
not have enough but the vm isnt able to reclaim fast-enough. Problem temporarily solved by setting
lower_zone_protection to 1024. Still I wonder why /proc/net/sockstat shows this:
sockets: used 1637
TCP: inuse 1761 orphan 179 tw 3743 alloc 1761 mem 54224
The send-buffer is set to 128 and the rcv-buffer to 16 so theoretically it should be 1637*144=235728
so I assume the buffers are allocated dynamically when they are really needed... I suppose the
slow-down wouldnt appear if the buffers are allocated statically. Is there any way to check this?
Chris
