In a PAM deployment on OpenShift, the directory for Git indexing, set in the org.uberfire.metadata.index.dir Java setting, is apparently not pointing to the shared PV. This was reported by Lyle Wang and Hiroko Miura ; as far as I could work out the version Hiroko was testing is 7.7, but I am not aware of any change in 7.8.
Adding "-Dorg.uberfire.metadata.index.dir=/opt/kie/data" significantly improves performance - apparently not just because of avoiding repeated indexing but also the indexing itself runs faster. Hiroko has provided the link to a log http://pastebin.test.redhat.com/897962 and two log files that I attach.
This surfaced when working out performance requirements as per BXMSDOC-6227, but this issue, if confirmed, is a code issue and not a documentation issue. If it is confirmed I would suggest considering a fix even for 7.8.1 but certainly for 7.9.
