2 indexers in a cluster and a single search head and separate cluster master/license master/deployment server all on windows 2019.
and have installed IT Essentials work version 4.31.1 and created the clustered indexes and enabled the apps I wish to use. After a few mins the web interface on my single search head grinds to a halt and everything starts running very slowly. Compute on the search head and indexers seems fine and I have 32 cores and 64 GB RAM on each. If I disable all the apps that come with the IT Essentials work package performance returns to normal.
