PostgreSQL will become much quicker if it can cache more data so you might want to add some RAM (go to 6 or 8 GB and maybe tweak your PostgreSQL configuration a bit) When we were still running virtual the web frontend machine had 8 GB and the PostgreSQL VM had 8 GB, both with 2 cores and things ran fine (granted, with only roughly 70 clients) - for us OSA became a lot smoother and more stable by switching it's backend from berkeley DB to SQLite ; I'd recommend this step to everybody using OSA. See <a href="https://www.redhat.com/archives/spacewalk-list/2011-March/msg00048.html">https://www.redhat.com/archives/spacewalk-list/2011-March/msg00048.html</a> on how to do this. - you might want to check if the machine is hitting I/O limits ; tools like vmstat can help a lot More CPU's doesn't sound like the solution, as only one core is pegged at 100% ; memory, disk I/O and maybe if it's a remote PostgreSQL instance network sound like more likely candidates. -- Jan-Albert <div dir="ltr" style="color: rgb(33, 33, 33);"></div> Jan-Albert van Ree | Linux System Administrator | MARIN Support Group MARIN | T +31 317 49 35 48 | <a href="mailto:J.A.v.Ree@marin.nl" title="" target="" style="font-family:Verdana;font-size:8pt;">J.A.v.Ree@marin.nl</a> | <a href="http://www.marin.nl" title="" target="" style="font-family:Verdana;font-size:8pt;">www.marin.nl</a> <a href="https://www.linkedin.com/company/marin" target=""><img width="16" height="16" style="border: 0px Solid ; " src="cid:image11bc0e.PNG@7381f0ab.439a5b40" alt="LinkedIn"></a> <a href="http://www.youtube.com/marinmultimedia" target=""><img width="16" height="16" style="border: 0px Solid ; " src="cid:imagee95bb6.PNG@4172e809.4c8a24e7" alt="YouTube"></a> <a href="https://twitter.com/MARIN_nieuws" target=""><img width="16" height="16" style="border: 0px Solid ; " src="cid:image4e3140.PNG@839b3c49.428e3613" alt="Twitter"></a> <a href="https://www.facebook.com/marin.wageningen" target=""><img width="16" height="16" style="border: 0px Solid ; " src="cid:image1ea6dc.PNG@d15869bd.46a0f4af" alt="Facebook"></a> MARIN news: <a href="http://www.marin.nl/web/News/News-items/Software-seminar-in-Shanghai-for-the-first-time.htm" title="" target="" style="font-family:Verdana;font-size:8pt;">Software seminar in Shanghai for the first time</a> <div dir="ltr" style="color: rgb(33, 33, 33);"> <hr tabindex="-1" style="display:inline-block; width:98%"> <div id="divRplyFwdMsg" dir="ltr">From: spacewalk-list-bounces@redhat.com <spacewalk-list-bounces@redhat.com> on behalf of Daryl Rose <darylrose@outlook.com> Sent: Thursday, October 13, 2016 16:54 To: spacewalk-list@redhat.com Subject: [Spacewalk-list] How to improve WUI performance <div> </div> </div> <div> <div id="divtagdefaultwrapper" style="font-size:12pt; color:#000000; font-family:Calibri,Arial,Helvetica,sans-serif"> I have 465 servers in my SW environment, and I keep adding more everyday. When finished, I'll have nearly a thousand servers in the environment. My SW server is a virtual RHEL 6.6, SW v2.3. I have four CPU's and four Gigs of memory allocated to the server. Whenever I select "Systems" from the main menu a single CPU pegs at 100%, and it takes several minutes for the page to come up. It appears that osa-dispatcher is what is using up the CPU. osa-dispatcher is often at 99 to 100%. Is there a way to performance tune SW? Can I configure SW to use all four CPU's, or should I add additional CPU's, can configure SW to use all assigned CPU's?
