Description

I investigated lock contention during concurrent page loading (PageLoader.loadPage).

There are two main producers of lock contention:
ComponentInstantiatorSourceImpl and PlasticClassLoader.

I created a patch for two top issues, see it in attachments.

There is still issue with PlasticClassLoader. I will report separate issue regarding it.

Sub-Tasks

• Lock contention in ComponentInstantiatorSourceImpl: Closed
• Lock contention in PlasticClassPool: Closed
• Parallel class loading: Closed
