High Performace - BigIp3600

Hi all !!

I do not have much experience on the F5 device and ASM module, So hope everyone advise on my case

Our customers are using F5 devices with Application Security Module, currently we are using Acunetix tool to scan the WebApp behind F5 and F5's performance increased high ( CPU ~ 65%; Ram ~ 85%; throughput ~ 25Mbps).

When we stopped to scan WebApp the memory's F5 still high ( > 80%); CPU (< 15%) and ThroughPut are decrease. Now we are performing in pilot enviroment not production and all current configuration (LTM, ASM) is basically.

So my questions :

- Everyone can give me some idea about CPU of F5 becasue CPU will increase over 65% when we using in production enviroment (I think that). So how much %CPU is good when using with ASM module ?

- Why memory of F5 still high ( ~85%) when we scan or stop scan WebApp ?

- When power on the F5 and not do anything, memory of F5 alway ~ 50% . Why ?

Here some informations of product:

Thanks and best regard,
