I shoot on a Canon XF100 that produces MXF MPEG2 files.
When I edited on Legacy FCP (a couple of years ago) it would import them pretty quickly without having to re-encode them to Prores.
Now that I'm in FCPX, it seems to take FOREVER to import, especially long clips (more than 10 minutes). They seem to import at real time. So, an hour and a half for an hour and a half video clip! I'm know I'm impatient but that seems way too long.
I've noticed other formats do not have this issue.
When I check the final FCPX file in the "Final Cut Original Media" folder, the files are now .mov but still MPEG2.
Try dragging the folder of footage into the event instead of using the import dialog. This works for our Sony FX6 MXF footage and does not copy/rewrap it to the library. This might not work with MPEG2 footage.
Sorry Tom, I missed seeing your question. I haven't imported MXF using the import dialog in a while and don't have any footage in front of me to test, but I recall it imported fairly quickly and was usable quickly but I could see the background process chugging along, copying and rewrapping into the library.

FCP must re-wrap (not transcode) certain formats which copies that media to the library. That process is normally fairly fast. I don't know why it seems to be so slow in your case. If the imported .mov files in your library "original media" folder are still MPEG-2, that implies they were re-wrapped, not transcoded.
However in general it's best to import using "leave files in place", but FCP won't do that for tree-oriented formats. IMO the best solution is use the 3rd-party utility EditReady and externally re-wrap the files, then import to FCP using "leave files in place". The rewrap preset of EditReady is extremely fast and combines all camera metadata, joins split files, etc. I've used it on various MXF formats but MXF is just the wrapper -- I don't have any MXF-wrapped Canon XF100 media to test. hedge.video/editready
EditReady is not just usable for this one case but for any case such as AVCHD or other tree-oriented formats. The latest version can also transcode from Blackmagic BRAW to ProRes.
