Update of Underlying Squid Engine to Support Multiple Cores
Starting with firmware release version 5.2.3, the underlying squid engine was upgraded from 3.1.06 to
3.2.0.7. This introduces support for multiple CPU cores and results in significant improvements in
proxy performance on Barracuda NG Firewall units with multiple CPUs or multiple CPU cores (F400
and higher). By default (
auto) as many squid processes (workers) are started as logical CPU cores
are available up to a maximum of 8. This setting may be adjusted in the
HTTP Proxy settings within the
Advanced view, however, Barracuda Networks recommends to leave the value at auto.
This feature has previously already been introduced in hotfix 438 for firmware version 5.2.2.
