Description:
|
The Job Statistics portlet takes a long time to initially load with 100+ jobs and 1000+ builds each. Thread dump shows the stack trace is mostly spent in RunList.size() which is being called in StatJobs.HealthStatus.getHealthStatus(). This forces every build to be loaded from disk when, looking at the code, all it needs to do is check if the list is empty.

Even after the initial load, subsequent requests still take several seconds due to complete traversal of every build for every job.
