An often overlooked trick to get better disk performance from your Azure Linux VM

This may sound obvious to many – my apologies to that section of my audience. However, as I engage with more and more customers complaining about not getting good read/ write IO performance on Azure Linux VM-s, especially when using databases like Mongo/ MySQL or Cassandra/ CouchDB or HBase, I see a trend. Typically, the engineering…

MySQL performance benchmark on Azure Linux: OS disk (ext4) vs RAID 0 array (xfs)

  Introduction   In an earlier blog post, I wrote about how we can configure an Azure Linux (Ubuntu) VM with a RAID 0 array of data disks and mount XFS on the array. The goal of doing this was gaining disk I/O, hence performance. In order to substantiate this claim, I am following up…


Set up Azure Ubuntu VM with XFS on RAID

  Summary: If you are running applications like MySQL / MongoDB / Cassandra / Kafka or any other custom application that accesses data disk(s) on an Azure Linux Virtual Machine frequently for storage or Disk I/O, you may consider using a RAID array of data disks to improve performance by increasing concurrency of reads/writes. RAID…
