grsecurity forums

Hello to all
2 servers here
Server1 - P4 @1.5Ghz 1GB RAM kernel 2.4.25 patched with grsecurity-1.9.14-2.4.25. There is no problems with transfer rates - Up to 15MBytes/ec. Load average is normal 0,3-0,5.

Server2 - P3(Coppermine) @333Mhz 768MB RAM kernel 2.4.25 patched with grsecurity-1.9.14-2.4.25. Here i am experiencing abnormal high load averages and slow transfer rates(0.3-0.9MB/sec - with clean 2.4.25 kernel normally i can down|upload with 5-6MBytes/sec). CPU usage is 100% almost all the time and transfers are lagging at random periods.

Both servers are running samba 3.0.2a-1 on debian unstable

Any idea?

did you try running a vanilla 2.4.25 on this machine? Did the load averages drop to normal levels with vanilla?

-Rik

Yep with vanilla everything is ok...

how many processes do you have running on the system?

can you try the 2.0 patch and see if that's any different?
there's a specific algorithm change in 2.0 that i think may solve this issue

-Brad

About 1k proccesses. I`ll try 2.0 later tonight
10x

What is vanilla?

vanilla = a plain kernel downloaded from kernel.org; nothing else patched in to it.
