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.
