I know DrF is most probably correct, but "call QLZARCAPI" would show
what the LPAR config "looks like" for processor setup.

So 725 is almost certainly 0.05 of a CPU, probably a Power8 server as
the smallest Power9 I have would be 850 for 0.05 CPU.

Clearly that's small and lower than the recommended minimum for 7.5 for
example.

Now will bumping to 1450 help? Almost certainly. Even if you ARE
uncapped, it will help a bunch. Every time a system goes back to the
queue for more CPU, it gets in line and when it gets time in the
processor the amount of time permitted is relative to the base CPU
allocation. Thus at 0.05 the smallest amount is allocated and when that
times out the process goes back in line again. Even at 0.10 the
allocation is doubled so right there it helps a bunch.

I am using a cloud system and I was set up with the lowest CPW

available.

It works in most situations except it is a little slow for websites
with a
lot of server side includes. This means that when a page is loaded

there

are 10 or more requests made at the same time to fulfill those SSI
requests
and it seems to overwhelm the CPU. (Think of it as 10 or more people
requesting a CGI web page at the same time).

Would a bump up from 725 to 1450 make much of a difference? Or is there
any tuning one can do to help?

I am thinking about changing the way the pages are developed to not
use so
many SSIs.. but they're so nice. :)
