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

[Ahmad Alzaeem]

Hi Amos , 
I think it got it woring with multi instance
I let each instance load some ports and each instance has its only kid1 process.

But im asking now where to do the cpu mapping ?

Is it done in squid.conf ?

Or for each separated instance conf file ?

Is my formula below  correct ?

cpu_affinity_map process_numbers=1,2,3 cores=1,2,3


thank you so much

Hi Amos , thanks for reply 

Regarding to your description

If I have 10K ips with 10k listening ports ......

Will each squid process handle 10 K ?
Or I need to distribute the ips/ports to each process ???

cheers

3.5.9 is the latest security release.

You wont get balance on the cores. They actually work *better* when unbalanced. It makes the core L2/L3 RAM cache work with closer to optimal contents.

With 3.5.7 or later run several Squid with:

 squid -n squid1
 squid -n squid2
 squid -n squid3
 ...

The "${service_name}" variable in suqid.conf will become that "squid1", squid2" "squid3", etc

You need to make your squid.conf contain:
 include /etc/squid/${service_name}-ports.conf
 pid_filename /var/run/squid/${service_name}.pid
 cache_log /var/log/squid/${service_name}-cache.log

... and so on for the other directives listed in <http://wiki.squid-cache.org/MultipleInstances>

Make the squid1-ports.conf etc config files listing your http_port's and a unique_hostname for each Squid instance. Maybe access_log as well.

Also set cpu_affinity for each instance to tie them to different cores.
