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
