[Spacewalk-list] Spacewalk performance tuning for deployments with 1000+ hosts

[Krzysztof Pawłowski]

I think that problem is rather in executing lineary tons of thousand sql
queries to database. Propably queries are per host and maybe they could be
executed in parallel ? I'll try to raise timeouts in tomcat and apache
configuration but this won't make this usable.
