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
??
???
