Or the transaction rate or application complexity has simply grown from
the original design and has finally exceeded their IFL engine(s)
capacity and they are now trying to determine the cheapest alternative
for increasing the CPU power available to z/VM and Linux.

Thank You Suresh,
Improper sizing of Memory, Paging and SRN parameters is a definite possibility.

Subject: Re: Question concerning Z/VM, Linux and General Processors
I agreed with Tom. GCP is set run at low speed though Linux can be hosted
natively on it. There may be something went wrong in initial planning of
Memory, storage sizing etc. Otherwise there should not be any high CPU usage on
IFL.

Yes, it can. Remember that IFL processors run at maximum speed, while
general processors may have been set to run at a slower speed,
depending on the model.
We seem to be experiencing high CPU usage and management seems to
feel
switching the
workload off of the IFL might be beneficial.
High CPU usage in the IFL?
