FusionReactor 9.2.2 released Mar 1 2023, can track query cache count per app, fixes memory issues
Note: This blog post is from 2023. Some content may be outdated--though not necessarily. Same with links and subsequent comments from myself or others. Corrections are welcome, in the comments. And I may revise the content as necessary.TLDR; In case you missed it, FusionReactor 9.2.2 was released on March 1, 2023, and among its new features it can optionally now track CF query cache counts per app (as I'll show). It also fixes an important issue of CF 2021 or 2018 "suddenly using a lot of heap memory" which was caused by a change introduced in FR 9.2 as released in mid-Jan, and 9.2.2 also adds new JVM args and UI elements to control the features related to that (as I'll show). There are a couple of other bug fixes/changes as are tracked in the FR release notes.
For some, that news is all they need to hear. For others, read on for more details (including why the delay in my announcing this).
