Over the years I have added some 40 JAR files to my jvm/lib/ext directory of my Domino server. Many of my customers have done the same thing.
It improves performance but mostly it is to prevent memory leaks.
But when upgrading to 8.5.3 FP3 the installer wipes the ext directory clean and replaces everything with the IBM jars.
So make a backup before!
If not it is always a good idea to test the backup strategy once in awhile.
