Cromwell 88 custom machine types are slower and more preempted than the cromwell 87 e2 machine types

[GregoryDougherty]

I built cromwell 88. Then I ran two large preemptible runs, one with cromwell 87 and the other with 88.

The e2 with standard machines ran faster, and was pre-empted less, than the n1 with custom machines.
11% faster, and 424 preemptions vs 276.

Many of the 424 were preemptions that happened really early in the run process of the task. So it may be that I just had bad luck with someone kicking off a large non-spot run while my 88 run was going but the 87 was finished.

But I've been advised that custom machine types are much more likely to be preempted than standard ones.

Would it be possible for you to default to n1 or n2 standard machines, rather than custom ones?

Thank you

Additionally, I really miss the logging 88 eliminated. With 87 I see the machine type allocated, with 88 I don't.

Is there some command line option for turning all the logging back on?
