Just bought a Mac Pro 12-core d700 and doing some video editing.
I imported a 1080p 60fps video, transcoded it to optimized (no proxy) added magic bullet looks contrast filter and renoiser and let it render. Footage is 30 minutes long.
Now I can see the system actually isn't doing much.. it's almost idle and the background renderer is really slow.
is it just me or is there something wrong ?
FCPX 10.3.4 on High Sierra
Editing off a WD Thunderbolt duo 4TB (250 mb/s max)
EDIT: the background render is 5hours in and still on 42%
There are all kinds of anomalies between High Sierra, FCPX 10.3.4 and various plugins. You can spend lots of time chasing a problem only to find it's an odd interaction that can only be resolved by updating FCPX (see below) and plugins and/or by reverting to Sierra.
I don't know of specific problems with Red Giant's Magic Bullet Looks and ReNoiser vs FCPX on HS, but I don't have those.
If you just bought a 12-core D700 new and it's still in the return window you might want to consider returning it and evaluating the iMac Pro which is released this Thursday. It is much faster than the top spec nMP plus apparently has hardware accelerated H264 encode/decode. This is a separate issue from your stability problem which could just as easily happen on an iMac Pro or regular iMac.
Re background rendering you normally don't need that. In some cases it can cause problems so I'd suggest turning it off and trying your edit operations without it. It's possible FCPX 10.4 may be released this Thursday with the iMac Pro but nobody knows. If so, that version of FCPX would be better suited to High Sierra, and updating FCPX on your current hardware might fix the problem.
Test results, 2017 top-spec iMac 27, Sierra, FCPX 10.3.4, 2 min 30 sec (1.8GB) UHD 4k material from vimeo.com/135670345
Output to UHD 4k (best performance): 1 min 4 sec
Create proxy media after import: 29 sec
Create optimized media after import: 1 min 9 sec
Separate BruceX test: 15.8 sec (background render off, fresh library, ProRes 422 output)
Test results, Martin's Mac Pro 6,1 12-core @2.4Ghz D700:
Martin, some of your above numbers are very roughly in line with my past tests on a 12-core D700 Mac Pro, but others are not. My previous tests showed the nMP was about 1/2 as fast at transcoding to optimized media (which you observed). However my "create proxy" test was also about 1/2 as fast on the nMP but yours was slightly faster. I don't understand that.
On the master file export test to 4k H.264 "faster encode", I expect the nMP to be somewhat slower but not 1/8th the speed. Please re-check your export settings, also make sure background rendering is turned off:
Video codec: H.264 Faster Encode
Resolution 3840 x 2160
The BruceX test is very sensitive to test procedure. I always create a new library, restart FCPX between each test, have background rendering off, and output to ProRes 422. I usually repeat each test 3x and take the average time (yes that's a lot of work!)
My previous BruceX tests on a 12-core D700 Mac Pro were around 17 sec.
Since you got the Mac Pro 2nd hand, you can be satisfied with it. Even today it is a good machine for multi-core CPU tasks and on ProRes media it is very fast. It is very quiet under high load, unlike my iMac.
