Web proxy generate 100 % CPU

[florinbro]

Web proxy generate 100 % CPU after 5-15 minutes from boot up on RB493. Web proxy service himself use 98 % as shown in profiles.
Restore from backup .. even with 2-3-4 steps ahead .. and same behavior.
this was happening on 5.26. Even after downgrade to 5.25 same thing.

any suggestion for solving the problem ?

how can I investigate this ? where can be seen what sites actually access the users ?

Proxy on a 493 is probably too much for it to handle.

Go to IP > Web Proxy.
What are Parent Proxy, Max Cache Size and Cache on Disk set to?

Click Cache Contents button.

if it works on 750 and 450 should work on 493 too !

Parent proxy is the IP of our Proxy Cluster, Max Cache Size it was setup from 20 000 to 36 000 and same 100 % CPU after few hours. Cache on Disk is not setup. Should be setup on disk ?

Click Cache Contents button.

Users access any site they want !

I thought maybe you were running the proxy on the 493 itself, without parent proxy, and that could cause high cpu.

No. If you’re using parent proxy, I don’t know if this would even matter…

After upgrading to 6.5 … after setup Max Cache to 20000 KiB … on RB450 and RB493 (setup to 5000 on RB750) … the machines works normal. Web proxy are using 0.5-10 % CPU.

For curiosity I setup max Cache to 30000 KiB and choose Cache to Disk … but this generate bigger fluctuation 10 - 75 % CPU and this makes overall CPU load to 100 % and makes machine slow responsive !

So .. it is not the same to Cache on DISK or Cache on Ram

Now is clear ! I do not know why someone who read not said so … probably others do not test it themselves
