[squid-users] how distribute squid loads to cpus and memories using SMP feature??

hi all ,
im trying to use smp feature on squid last version 3.3.9 compiled ,
i have server of Delr210 with 8 G rams and i have cpu quad core 3450 intel
xeon ,

==============================================================

so ,
my loads insquid is as below :
1-disk cahing "i have 4 hardsisks each with 90 G cache dir""
2-memory caching " i have 8 giga memory installed "
3-web filtering "using ACLS"
4-custom ACLS based on srx ips

 i read http://wiki.squid-cache.org/ConfigExamples/SmpCarpCluster

Q1-how many workers do i need ? " from /proc/meminfo i have 8 cores "
Q2- what process is better to go frontend and which loads better to be in
backend ??

regards
