Description of problem: Work with group with 10'000 and Satellite's load go up, either page takes several minutes to load or end in "temporarily unavailable" error due to timeout. Version-Release number of selected component (if applicable): rhel54 x8664, 99gigs of ram sat530 rpm -q spacewalk-java-lib spacewalk-java spacewalk-taskomatic spacewalk-java-lib spacewalk-java-lib-0.5.44-45.el5sat spacewalk-java-0.5.44-45.el5sat spacewalk-taskomatic-0.5.44-45.el5sat spacewalk-java-lib-0.5.44-45.el5sat How reproducible: always during working with 10'000 systems Steps to Reproduce: 1. go to 'System Entitlements' 2. select all system 3. remove / add provisioning entitlement Actual results: See load on Satellite server go up, either page takes several minutes to load or end in "temporarily unavailable" error due to timeout. Expected results: Page loads in reasonable time Additional info: you can simulated huge number of machines by running something like this: 1. create 30 system groups 2. create activation key 1-1 to 1-30 which add system to system groups 3. run on few clients: for a in `seq 1 30`; do { for b in `seq 1 200` ; do rhnreg_ks --activationkey=1-$a --serverUrl=http://gs-bl460cg1-01.rhts.bos.redhat.com/XMLRPC --norhnsd --force --profilename=$b-`hostname` ; done; } done if you have more then 10'000 try steps in reproduced
