High CPU usage?

Hi,     one of our ASM biggest customer is worried about the performance of his new LTM + ASM machine. They own a pair of 6900 running 9.4.8.HF4 with LTM + ASM (full of licensed capabilities). A...

Hi,

 

 

I'd suggest opening a case with F5 Support. I'd be quite interested in hearing what they have to say on this as I've always found it difficult to get any concrete information on what ASM is doing with its CPU cycles and memory.

 

 

If you get anything useful on this from F5 or otherwise, could you reply back?

 

 

A small note: I believe the ASM CPU utilization graph doesn't show cumulative stats for ASM CPU usage--just the amount of CPU used by the BD process(es). Also, I think the top output should show a percentage of all CPU's. So if a single BD process is using 10% of all CPU per top, it's actually 40% of a single CPU as BD can't run across multiple CPUs (or CPU cores).

 

 

Thanks, Aaron
