New Server Infrastructure Halves Server Process Time
Recently I was analyzing and troubleshooting the performance of an ADF application. Much was already improved before I came. Due to a very recent new hardware/infrastructure environment, the server and database process time was nearly 50% faster after migration. In this blog I want to show you the impact it had on the total server process time of HTTP requests. Such a sudden improvement is visible in the ADF Performance Monitor in a glance, and in Week and Month trend analysis overviews. Maybe you need to investigate your hardware/infrastructure as well ,and consider an upgrade; if your hardware/infrastructure is relatively old, if your machines are full, or if virtualization software is not implemented efficiently.

Monitoring with Percentiles
What is best metric in performance monitoring – averages or percentiles? Statistically speaking there are many methods to determine just how good of an overall experience your application is providing. Averages are used widely. They are easy to understand and calculate – however they can be misleading.
This blog is on percentiles. Percentiles are part of our recent new 7.0 version of the ADF Performance Monitor. I will explain what percentiles are and how they can be used to understand your ADF application performance better. Percentiles, when compared with averages, tell us how consistent our application response times are. Percentiles make good approximations and can be used for trend analysis, SLA agreement monitoring and daily to evaluate/troubleshoot the performance. (Lees meer..)
