hi ,
i just want to let acl checking far from process # 1
with config above ,
i pumped about 500 users and i monitored my cores
i found that process # 1 is about 30 % and all others about 10 %
i think if i let acl verification far from process # 1 , it will make better
for squid !!!
is my suggestion better ??? or let acl verification shred on all processes
??
???
