“Performance testing is not a one-time event”

Quote By Theresa Lanowitz

What’s New

  • A new load testing tool launched by Apica along with online resource named that combines all Apica load testing tools and services into a single platform.

    • Automatically compare test response data to originally recorded responses to avoid false positives
    • Available with 30 command lines to directly automate test generation without using GUI
    • Extensive reporting which comes with 24 standard charts plus a custom PDF reporting tool

  • Continuous Performance Validation (CPV) is a new platform provided by Neotys for load testing and performance monitoring for the application lifecycle. The solution consists of the following:

    • NeoLoad for load and performance testing
    • NeoSense for 24x7 synthetic monitoring
    • Integrations with CI & APM tool

Knowledge Base

Most Important Parameters for Server Monitoring

Impact on Server Performance
Server will no longer process more work & throughput flattens if CPU hits 100%
80% or more CPU utilization for each processor for long period of time
Memory shortages and leaks leads to application instability
Memory leak occurs if Process\Private Bytes and Process\Working Sets is increasing, and Memory\Available bytes decreasing
Processor remains idle while the disk is being accessed
I/Os per Disk = [Read + (4xWrites)] / Number of Disk If calculated I/Os per disk exceeded Disk I/O capacity of Server, this would lead to disk bottleneck

Commonly Used Server Monitoring Tools on Windows platform

  • Performance Monitor: Examine how programs you run affects server's performance. It uses performance counters, event trace data, and configuration information, which can be combined into Data Collector Sets.
  • Xperf: Provided with Windows Performance Toolkit. It is an advanced tool that provides detailed performance and system data.
  • Reliability Monitor: Measures hardware and software problems and other changes to your computer. It tracks the history of your computer to provide you the information for application crashes, hangs, or Windows blue screen.
