Can MERGECAT performance be improved by altering the buffer space

If you have a lot of VSAM, probably not. As I recall, doing a large
repro mergecat with a lot of VSAM was very slow, but it was mostly
due to the need to go change every vvds entry.
In other words, I don't think you'll get a lot of bang for your buck.
