Description of problem:

Display channel details is slow on channels with many packages.  With a fedora9 channel with around 9000 packages I'm seeing the channel details page take minutes to display.  Example when running over VPN this is taking over 5 minutes to display.  When running with a local DB connection it's taking over 1 minute to display.

Version-Release number of selected component (if applicable):
Spacewalk 0.2

How reproducible:
Always

Steps to Reproduce:
1. Create a custom channel with over 9000 packages
2. View channel details, ChannelDetails.do
3. 
  
Actual results:
With a local connection it takes about a minute or more to load

Expected results:
Should load quicker

Additional info:
I think this might be slow because of the below line in ChannelDetailsAction.java:

request.setAttribute("pack_size", chan.getPackages().size());
