Solr 7.3.1 and Red Hat Hypervisor 4.4 Performance Problems

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
