I ran into a similar case, which turned out to be that our Windows anti-virus package was incorrectly configured on the new server: it was forcing a complete check on all RMAN files, while the old one treated them as a low risk operation.

Is your data storage configuration the same compared old situation? A lot of time is spend waiting on IO for large resultsets. If some (sw) raid is configured in the new situation where the old situation was not, I can imagine that returning resultsets may take considerable more time.
