Performance problems beacause of python?

[sputnik]

Hello together,

I am currently running FreeNAS 9.1.0 with 8 GB RAM.
My Server Filesystem is ZFS and i have 8TB of Harddrive Space.

I never had performance problems with my NAS but now it seems that i have not enough RAM.
This is the Output when i use "top".

Code:

I am running 5 Jails. But it seems that Python uses a lot of RAM. I don't know if this is normal. So I am asking if this is normal or a sort of memory leak.

I should say it's perfectly normal and it shows the same memory usage on my FreeNAS server (with 10GB), in any case you don't appear to be using any swap - why do you think you don't have enough RAM?

I thought it was not normal because when i reboot the NAS it shows 500M Wired RAM. Because of that i thought it is a memory leak.
