Performance Tuning in Liferay – Part 3

You will find the part 1 & 2 of this series on Performance Tuning in Liferay here:

Further to above, find below some tips on Performance Tuning as part 3 of the series.

Explore Java 11 instead of Java 8 with Liferay. Java 11 has performance and concurrency improvements. Check your compatibility matrix for compatibility.
Explore various types of Garbage collection options – In my experience for certain scenarios G1 is especially helpful: Types of Garbage Collector in Java – Javatpoint
Explore fragment caching button and option if you are using fragments
Fine tune your Heap Size, analyse your heap dump, queries in Glowroot, MBeans in Glowroot to change EHCache values in Liferay – Make this an ongoing exercise
Explore fast load css, fast load javascript, minifier, no pragma and cache.browser.disabled, users.update.last.login configurations
Explore configuration in control panel for documents and media for private and public cache
Upgrade and map to latest quarterly release, generally they have improvements
Explore row lock error, Ora-1795, etc. settings in help center which cause known issues while scaling and workarounds for which are added in Help Center
While doing performance tuning, do a warmup with low users to fill up cache of Liferay before actual testing – clear all 4 types of cache in CONTROL PANEL -> SERVER ADMINISTRATION when you make web content or other changes for them to reflect properly before load test
Be cognizant of load times on JMeter and browser both – different configurations affect both differently
