About HTTP Proxy performance

robertone64
Hello everibody

I have a ASG120 rev4 / 2GB RAM / V9.101-12 / Home license

I have enabled Intrusion detection, Endpoint Protection, Remote Access and Web Filter in transparent mode, no caching enabled.

The Web Filter performance is very slow, sometimes opening webpages gives a timeout error, sometimes only extremely slow access.

tryed to disable all module except WF without success, disabled AV in WF and all thing i can disable but wf remain slow, if i disable wf all is ok, download and url access return regular.

Anyone have Any idea ?

Thanks for your Help

Roberto

PS prior to update to 9.x the web proxy was ok
Average CPU use : ~5%, avg RAM 36% w/o filter, ~50% w web filter enabled
