No need to skip any tests :) Your build is probably quite CPU-hungry because I see that those slow builds happened on VMs which run on specific Hyper-V machines (AWS "bare-metal" instances we instantiate during load spikes or maintenance) which has a little bit lower CPU clock rate than the ones in our datacenter. We set your builds to avoid those VMs. Also we increased your build timeout to 90 minutes, just in case. You should be good now. And please ping us anytime you need.
