Our monitoring system starts worrying about the load average if it ever
goes above 0.75*number of cores. In your example it looks a bit like
you paid for 15 more cores than necessary.

Especially at the lower end you have to take the load with a large
grain of salt.  Lots of short running processes (like a make run) while
make the load fluctuate.  But even things like it taking a while for
your disk cache to reach steady state after a reboot can mean that you
see a higher than normal load for a while.

But 0.88 is really nothing to worry about. Perhaps it is just slower
core or a slower memory bus.

Have a nice day,
