Problem running test app of bhive #14

Open teoaivalis opened 1 year ago

teoaivalis commented 1 year ago

Running the test of bhive in my processor (kabylake) I take the following result.

Trying the same on a haswell processor the result is the following

There is no throughput produced. The messages of bad file descriptors are the same in both processors.

Trying it on a sandy bridge which is older than haswell it run correctly and without all these messages. On brodwell and skylake it does not run at all. Have anyone any idea where this problem comes from?

Thanks.

What do you see when you run perf stat on the haswell machine?

I have not tested it on a haswell machine. Trying perf stat on brodwell machine it gives me the following

In both cases throughput is produced. Can we conclude which the problem could be?
