The systems query is very intensive on the DB. How is your oracle db server performing. Also you may want to add more vcpu vram to the spacewalk server or increase the number of db connections.
Out of curiousity why have so many proxies ? i’m surprised your master returns that query at all ;) if they are all remote sites I prefer to have a spacewalk instance at each location or at least minimise the use of proxies. It’s not a “single pane of glass” so to speak but makes troubleshooting/management and tuning much easier. Performance is obviously way better with spacewalk managing less hosts per instance.

We are using Oracle Linux 6.5 for our Spacewalk master with the Oracle Spacewalk 2.2 release. We have multiple Spacewalk proxies, each will manage 1k instances up to a total of 6 proxies. We have a separate Oracle db server running 11G R2. What we are seeing is a long lag when accessing the Systems Overview page. We've tried all the standard tuning for Java and tomcat, all the recommended tuning for Spacewalk and Satellite configurations with no change. When we have 100 OL instances registered it takes 5 sec flicking between Overview and the Systems tab. When we increase this to 350 OL instances we see the lag jump to 15 secs, then increasing up to 1100 OL instances this lag is up to 70 secs. This is not going to be workable when we start increasing to +5k instances.
