When it was first installed on my zLinux servers, BESCLIENT used 2-5% of the CPU available to each guest. We didn't have the extra CPU for this increase on 26 guests. I contacted the team that implemented it and they were able to tweak a parameter that reduced the CPU overhead to less than 1%. That was several years ago and I don't know more than that. The person who made that change is no longer with the company and I doubt that anyone else knows what he changed.
I believe the change was made outside of the zLinux guests, at the server that gathers all of the information. I actually installed BESCLIENT as I have root access and the person who made the change did not have any access to the servers.

We began an investigation checking recently changes on the LPAR's and the guests. The only thing we found is that inside all the guests the BESCLIENT was installed. Although it the process doesn't show high CPU utilization, we turn it off and the VM's stabilized. Do anyone has similar issue with this product?
