Slow browsing when enabling content filtering

[kjellover]

When enabling content filtering on a MX100 (MX 18.107.10) the users complain about very slow browsing. It is almost useless.

I found some other complaining about this, but no real solution (as far as I can see). Without the filtering the utilization is between 10-65% and normally not more than 120 Mb/s download.

Is there any solution to this?

What all categories are you selecting/using?  That might be part of the issue.

I have tried both enabling several and only one (Pornography). There is no difference.

The same applies when eanbling one or more threat categories.

Without knowing more details about your network/setup/configuration it would be mere speculation on our part.

Maybe the troubleshooting link below can be of help to you.

MX Sizing Guide & Principles

How many devices (clients/users) does your MX support?  
Have you set your WAN uplink bandwidth limits to what your ISP provides?  
What is the global bandwidth per user set at?  

Those would be the things I would tend to look at first because it's causing such a slow browsing experience.
