Squid very slow after upgrade squidguard 1.2.0_1-1

[potechi]

I've using Squid + SquidGuard about 6 month without problem.
Recently I upgrade SquidGuard package to v1.2.0_1-1 and my problem begin, proxy become very slow. It take more than 5 minutes to open yahoo. If I disable SquidGuard proxy speed return to normal.
I use pfSense v1.2, Squid v2.6.18.1_06 with local auth, SquidGuard v1.2.0_1-1 with Shallalist, Lightsquid v1.7.1.
Is there something I can do to make SquidGuard usable again?
Thanks
