The explanation is not sufficient.
You mentioned that merging takes 24 hours, so I would expect that directing
merging will same you quite some time.
Feel free to provide some 'perf report' and I can make some suggestions based
on that.

I'm still missing information like:
- how long does it take the training run?
- how many parallel runs do you have?
- what's the average duration of a process?
