Hi all,
we were running VuFind-System with Solr 7.3.1 on OpenJDK 1.8.0_275 in a
VM hosted on a HP BL460 G9 with Haswell CPUs for quite a while. When the
data center upgraded the Red Hat Hypervisor to Version 4.4 (RHEL 8
based) we observed a massive performance degradation on import with
SolrMarc (about factor 4) that so far we could only solve by migrating
to a different blade with Skylake-CPUs running a RHEL 7 based Hypervisor
again. Is anyone else running Solr on a Redhat Hypervisor based VM and
observed a similar behaviour?
Thanks a lot, best regards
Johannes
