Internet Performance issues

Not applicable

Good Morning Everyone

We recently installed a new PA-500 with OS 3.1.4 loaded. URL Filtering was disabled. After enabling URL filtering internet speed degarded to the point of it takes 10min to open a site like google.... hiting refresh once or twice will open the site imediatly without any problems. Sometimes sites only gets loaded half. After reading multiple discusion I upgraded the OS to 4.0.3. The problem still exists....

Internet bandwidth is not saturated. (first thing i checked)

URL filtering is only set to alert by default onto the Inbound and Outbound policies. The only other policies is to block social networking applications.

What are we doing wrong?

Thank you in advance!

I have same problem, but only when SSL decryption is enabled. What about you ?


Good Morning Lardsa

At the moment it is a mix of sites (SSL and normal HTTP). It is not site specific, thats the weird part of it. I am allmost at the point of removing URL filtering (inluding the license) to see if Internet speeds restores! I hope PA support can asisist before I go to such extreame.

Busy checking on the SSL decryption (thanx)

Also note that if you have Dynamic URL filtering box enabled in your URL Filtering profile, it can lead to big slowdowns if your PA Management IP is not allowed to get updates from Bightcloud directly (5 seconds timeout). I experienced it myself.

Hi Lardsa

Dynamic URL filtering is not switched on and SSl Dcryption is not configured (unless I am overlooking it)
