hi ,
i have made a test for squid withing 30 minutes and ive logged alot of
things during working :
1st of all , the current server is 8 g ram and quad core cpu " 8 cores "
here is squid performance and degredation with time :
<http://squid-web-proxy-cache.1019090.n4.nabble.com/file/n4663169/237842408.png> 


as we see from graph , squid is fine as 1st starting and after some time
degradation start untill it reach down !!!!
also from grahp we note the cpu loading , not congested to specific cores ,
i see its fine .

note to hint that during the squid running the cpus cores was fine and
normal except free ram is getting decreasing !

@Alex , during to ur question , the cpu dissipation was jumping to cores
during top and pressing 1 then c
i monitored it and cpu dissipation is normal !
also ,
@Alex, ive disabled "named" service of my server  and let squid look to
8.8.8.8 for dns resolving , i mean i dont want it to be makking problems .

@Alex , about the "vary object loop" which i posted before , i found that 
when i define cache dir , i dont see this issue in logs , thats why in my
squid.conf below i configured only 1 G  for rock type  and 1 drive.

@Alex , ive reduced cache mem , and cache dir , and put mem pools off ,so
that we dont face problems in memoery ,but not sure if what i did is fine or
not.

here is squid.conf file :

=========================



just to hint , the free memory before using squid is 1 g  and after some
time   the free is about 200 M
could this be the problem ???
i did my best to let squid far from memory problems .
=========
currently i stopped squid and want to fix the issue before using the other
servers and pump more users

regards
