Your new script seem good but may be need some more tune to get better hash.
Can you try to add this to the script :
"sudo sysctl -w vm.nr_hugepages=128"
Yeah, i know about this issue. Actually, when i originally setup the script i did a lot of benchmarking to find out the optimal settings for the VMs in the azure-cloud. This hugepages-setting did not make any noticeable difference, so i did not bother including it in the script. I think this setting is mostly useful if you are mining on a real machine (maybe then you get that +20% hashrate that is mentioned on some mining-guides). Since with azure we are always inside a VM the effect is not there.
But you are right, the messages in the log from xmr-stak do not look good... since the setting also did not have a negative effect, i will include it in the script.
Thanks for your suggestion!
