Currently we are suffering from high CPU on compression en de-compression on our CIFS only filer. A sent perfstat.out to Netapp states that the CPU is working hard to decompress files while accesing them.
Is there a way to monitor compression en de-compression action with specific counters in DFM, or command line?
And what are the counters to look at? When do we reach a bottleneck, so we need to turn it off.
Users experience slow CIFS access on this filer. Sometimes it is slow, some time it is fast. There is not really a pinpoint on exact time.
