Hello Dear Sir

I redirect some http traffic to squid ( 90Mbps) and i found TIME_WAIT is
20840 and one of squid process is 57%

whether it will be normal condition ??

Whether we can balance cpu processing capacity

for full squid process !

Because we use squid 3.5.2 and use cache_dir rock part . Maybe squid
3.5.2 require to do automatic scheduling at full cpu core

i don't know whether i can use taskset for squid 3.5.3 as squid 2.7 ??


if possible , please give me some advisement
