I feel it depends on your AEM set up too. Below documentation from the Adobe gives an idea on the performance based on the set up you might have

Also in the same post https://experienceleaguecommunities.adobe.com/t5/adobe-experience-manager/aem-author-heap-size-error/td-p/400184 given by @jagadeesh_prakash

please check the reply from @Jorg_Hoh reply on memory issue

To understand the root cause for slowness, I would use the following approach:

* enable Garbage Collection logging on the JVM and monitor the GC behavior.

* quantify "slowness": Determine "slow" requests and make it actionable (what makes a slow request "slow"? Response times over 1 second?)

* check the periodic threaddump and search for patterns; correlate it with observed slowness (slow requests). It's definitely best if you could reproduce this in a lower environment and attach a profile to it to understand where the time is spend.
