[squid-users] squid with SMP registeration time out when i use 10K opened sessions

[Ahmad Alzaeem]

Hi amos I did , but can u tell me why that happened ??
Look @ my cpu cores for squid when it has high traffic :

  1  [####*********************************************100.0%]     Tasks: 29, 4 thr; 6 running

As you see , the 5 instances has about same loading , but it seems  the cpu mapping is not working ok !!!

I did add the command 
process_numbers=1,2,3 ,4,5cores=1,2,3,4,5

to each instance of squid !!

what coud me doing wrongh ?

or how to test if there process got the cpu mapping as ok or not

thanks a lot

Each separated instance file needs a different mapping to use your 15+ CPU cores.

Think about it: you are dividing cores up between Squid instances.
