Coding is very slow

Thanks for the logs. I can't see anything obviously wrong there. It would be interesting if you could send another log after ticking the "Timing" checkbox under "Log" in the advanced preferences. This will fill the log with some more information related to the frame queues.

It's probably not a DOM problem. I found that other video editing software also has the same issue. Before this problem occurred, I upgraded the BIOS of my computer and reinstalled the system. It may be related to the system or a protective mechanism that was activated after reinstalling the system. Thank you for the helpful answers from Carl and Carsten.

Thanks for reporting back!

When I bought my 'second' second-hand HP Z600 dual xeon system, I installed the OS from scratch and looked up HPs website for current drivers. I was surprised to find a very recent BIOS update. So, I installed it. Very quickly I learned that this update was targeted at the spectre vulnerability of these XEON XC56xx processors. When I compared DCP-o-matic encoding performance with my 'first' second hand Z600 which did not have that BIOS version installed, I immediately noticed that this BIOS update caused a severe slowdown while encoding. Luckily, I was able to find a way to downgrade the BIOS to the latest version before the SPECTRE patch, and encoding speed was back to normal. I only use this system for DCP-o-matic, RIPs, etc., so I never bothered about SPECTRE.

Yes but unfortunately I am using a MAC Pro 2012 5.1 and upgraded boot rom Unfortunately so far there is no way to find a way to degrade it and it feels like the computer has lost its value
