Not really. That's supposed to be what the "Performance" row describes. Although SSWE was much faster in my case, I don't think the slowness of the program with Win32::OLE can be blamed on the module. I'm certain the speed depended much more on Excel XP (that's what I tried to convey by saying "depends on the underlying COM code"). I'm also guessing it had more to do with how I wrote the program.
