Thankx amos that was great ... Many many many thanks for you . Last thing , if I use basic_ncsa_auth for the 10 K ports Do you think it will have a lot of cpu consumption ? I want the ncsa auth , but im not sure if it take a lot of cpu Waiting ur suggestion Thankx again -----Original Message----- From: Amos Jeffries [mailto:squid3@xxxxxxxxxxxxx] Sent: Wednesday, September 30, 2015 3:46 AM To: Ahmad Alzaeem Cc: squid-users@xxxxxxxxxxxxxxxxxxxxx Subject: Re: squid with SMP registeration time out when i use 10K opened sessions Scalable Multi-Process (SMP) Squid is multi-process. What you are doing here is running 5x collections (instances) of Squid processes (plural!). squid1.conf cpu_affinity_map process_numbers=1,2 cores=1,1 squid2.conf cpu_affinity_map process_numbers=1,2 cores=2,2 squid3.conf cpu_affinity_map process_numbers=1,2 cores=3,3 squid4.conf cpu_affinity_map process_numbers=1,2 cores=4,4 You have now run out of cores on the machine. So perhapse splitting into 5 instances was not a great idea. Split the ports into groups of 2500 instead. Although a 4-core machine is very tiny to be running the kind of workload 10,000 listening ports can be expected to receive. Sorry I assumed (wrongly) that to be needing 10k ports you had hardware like a 8/16/32-core machine for processing it.
