Performance Optimization Always Matters

By:


Performance bottlenecks are the bane of admins. They negatively impact an application’s quality of service, and can lead to nights and weekends filled with troubleshooting and remediation.

Add in a layer of virtualization and the bottlenecks usually bleed over into misconfigurations, such as co-stop issues in vSMP VMs when one vCPU is sufficient, or over-allocation of memory when fewer resources would have sufficed.

One of the top independent virtualization bloggers, Vladan Seget (@vladan), writes:

Every admin I meet puts performance on the first… place of his priorities. The other priority is disaster recovery. Depending [on] the environments, admins usually prefer to deliver [the] best performance, but [have concerns] about fast backups (and recovery) too.

To address these challenges, Vladan recommends becoming more knowledgeable about virtualization, and using the right tools:

Some of the tools integrate a possibility to detect configuration changes in the virtual environment. It means that you can see what changed the day that the performance started to be bad.
