Responding Slow when opening an application

Computer slowdowns can be traced back to either Hardware (failing drives) or software (corrupt flew) as sources.

Often strange behavior can be solved by deleting the User/Library/Preferences/ .plist file(s) with the applications name in it. Cache files from the same location could be corrupt. That the files took a long time to download might be a checksum error (corrupt files again).

Corrupt fonts and not enough free space or fragmented HDs can also cause freezing, lagging or slowness.

Adding a new peripheral or having peripherals connected can slow computers.

Sometimes creating a new user account will expunge the corrupt files… in which case extreme care and time in moving back a few "must have" files from the bad account at time may point out the culprit.
