Hello, 

We are experiencing speed problems with pfSense+squid in high traffic load 
conditions. 

This pfSense has squid+squidGuard+HAVP (squid configured in transparent mode 
and HAVP configured as parent for squid, as defined in the pfsense wiki) 

pfSense has also been tuned with the following system variables: 
kern.ipc.nmbclusters=32768 
kern.maxfiles=65536 
kern.maxfilesperproc=32768 
net.inet.ip.portrange.last=65535 
kern.hz=100 

Moreover, squid has the custom variable "redirect_children 20" because while on 
high traffic load conditions, the default children (used by squidGuard) were 
not enough. 

After some months of tuning, we cannot achive a good configuration (if 
possible) with it, and disabling transparent mode (and thus, avoiding traffic 
to get squid) is the only way we found to avoid the speed problems. 

There a speed limit for squid on pfSense or any configuration parameter i'm 
missing that can affect preformance? 

Thanks
