Profiling in jprofiler, using jmeter headless test on large test server, running customized ofbiz 10.4 (no customizations in this area though) ... 200 simultaneous users; 4 on each of 50 tenants that's where problems start to occur.
Response times for page requests get very slow up to 15 seconds with 100 users, 2 per tenant over 50 tenants. With 200 users I see 199 threads blocked and 1 running, this results in all the requests timing out. I am new to jprofiler but it looks like it is related to on FreeMarkerWorker.renderTemplate the monitor where the deadlock is named org.apache.commons.pool.impl.GenericObjectPool
