Re: Management Server sluggish

Hi Sib,

 

The management side of the 2000 & 4000 series is notoriously slow (look at the wait time on your cpu!)... I advise taking a look at this article:

 

https://live.paloaltonetworks.com/t5/Management-Articles/Steps-to-Reduce-MP-CPU-on-PA-2000-Series-an...

 

Also it has been noted that an update to 7.0.x has improved the commit performance on these devices.

 

hope this helps,

Ben

Re: Management Server sluggish

There is no real fix or solution, the problem is these 40xx series have 1GB management plane memory.

See the swap usages there are extreme compared the the real installed memory. .

It is the same problem the PA500 faced, but for the PA500 is a memory upgrade kit available.

And "new" PA500 come with 2 GB standard.

 

The memory for the PA500 is standard  "pc" memory.

 As mentioned before for the PA500 is a upgrade kit, for the 40xx series there is not.

but i know some people that upgraded a 4020 lab FW to 2GB with normal "pc" memory.

And it just works fine, but warrenty void en no support.
