Degraded performance container vs vm (-80% !!!)
I have still with mesos 1.9 degraded performance, any help to sort this
out would be nice. Makes me also wonder if others have bothered testing
this or not? I am testing still with mesos and thus have mostly a
default setup.
Previously when I opened this thread, there was questioning about
resource differences between the vm and container. This is not the case,
the vm has allocated 1 vcpu. To counter eventual memory issues I try to
use the dns cache by requesting contstantly the same 2 domains in
files-2.tst.
