Traffic Parrot 5.16.0 released, whats new?

 We have just released version 5.16.0. Here is a list of the changes that came with the release:

Features

• Select handlebars helper CSV file caching. When you set

  trafficparrot.virtualservice.handlebars.select.indexAndCacheCsvFiles=true

  the CSV file loading performance will be significantly improved.
• Supporting large number of CPU cores. When you run Traffic Parrot on many cores (40 or more) it would fail to start and report an error

  javax.servlet.ServletException: java.lang.IllegalStateException: Insufficient configured threads: required=212 < max=200 for QueuedThreadPool[qtp318353283]@12f9af83{STARTED,8<=168<=200,i=0,r=20,q=0}[ReservedThreadExecutor@71b3bc45{s=0/20,p=0}]

  The fix is to increase the number of threads Jetty can spin up. This was done by exposing two properties to configure HTTP Jetty server thread queues:

  trafficparrot.gui.http.queuedThreadPool.maxThreads=200
  trafficparrot.gui.http.queuedThreadPool.minThreads=8

• Upgraded Http client from 2.6.2 to 2.7.0
