Filip Brychta resolved SWSQE-360.
---------------------------------
    Resolution: Done


I did not find any issue with b17. My theory is that b17 is just slower than b20 because of the disk. b17 has just one physical disk but b20 has 4 physical disks in RAID5 which is much faster. I used http://git.app.eng.bos.redhat.com/git/jon-utils.git/plain/jonlab/scripts/measureDiskIO.sh to compare performance and difference is really significant (multiples). So starting 20 pods on b20 takes less then minute but on b17 up to 3 minutes which is probably expected. I suggest to use b21 with RAID instead of b17 for production cluster.

> Some pods failed with  Error, ran for 13 seconds
> Failed  	Error: context deadline exceeded
> Problem is visible when starting more pods at once (e.g. 20)
