Concern about memory utilization

I am running a single S650 with 6.0.0-542, just upgraded and rebooted last night. I currently have 85 total client connections ( 3 active), 160 server connections (3 active). Response time is good, bandwidth utilization is only 804kbps average. In other words, in my opinion, I am not hitting this device very hard. My concern is that memory utilization is showing between 65% and 85% under load. Is this normal, or do I need to be tweaking something?

Deployment Topology = Non-inline
Web Proxy Mode = Transparent
IP Spoofing = Off
L4 traffic monitor is enabled, but not networked using the T1 and T2 ports yet

Thanks for any advice

You're right, you're not hitting your device very hard.

The memory usage can be misleading, as the software pre-allocates as much memory as possible, and also holds objects in an in-memory cache in addition to the on-disk cache. So even on a lightly loaded device, memory usage will show a reasonably high percentage. It's likely not the bottleneck unless you see it start to run 95% or higher for a period of time.

So yes, what you're seeing is normal.
