Benchmark Tests on VPS – Part II

In this post are the results of running a few more benchmarking tests on the KVM VPS’es machines. In particular, running the dd test and also a failed attempt at running bench.sh.

Results of ‘dd’ test

Command: sudo dd if=/dev/zero of=test bs=64k count=16k conv=fdatasync

This is the result that surprised me the most, so I ran another test, with similar result. An internet search led me to this article on cyberciti dot biz, so I ran two additional runs, as follows:

Hmm… why is this happening? now that makes my homework for the weekend 🙂

Bench script: bench.sh

Surprisingly, bench.sh script resulted in hanging once the speed tests began to run. Here are the results:
