Crystal Slow Loading in LBI

We've been using LBI for almost a year. We have crystal 2008, and we develop front ends using .NET. Never had any problems.

However, suddenly with a few new employees we have seen .rpt files take MUCH longer to upload during the re-publish process......and then furthermore take MUCH longer to load the .aspx front end called from the report Events in LBI.

I have already ruled out EVERYTHING, and isolated the problem to the .rpt files themselves....but there has to be a LBI component here, because we can run the reports within crystal with 0 issues. We can also load the front end screens with 0 issues (very fast).

I can take an .rpt file, upload it, and observe the issue
Then I can start a fresh .rpt, point to the same data source, re-publish it and the issue is gone.

Re-publish the original .rpt, and the issue is back.

So granted the .rpt is the central issue.....but WHAT IS IT....about the .rpt that LBI doesn't like?

Has anyone experienced this? *(Specifically LBI's capability to fetch the front end URL and load it...because that is the primary concern it seems)*

I am basically at the point where I'm going to have to take a .rpt that LBI loads the front end for fast...... and a .rpt where LBI loads the front end slow and run a diff at the HEX level to figure this out, so any help is appreciated.
