Im trying to re-index the blockchain to avoid having to download it again (slow connection).

Its taking days. Im using Linux and the processor use is under 10%!
Does anyone know how to increase that? I've adjusted the DBcache size up very high and tried out using the Error check threads that are available in options and when I launch Bt caore it runs at 50% for a while and gradually slows down to under 10%.

Does anyone have any tips to speed this up? Surely it should be at 50% more or less all the time? !00% would be great.
The disk use isnt very high either.

FWIW - I've done informal monitoring on my PC as it's been syncing Bitcoin Core for the first time.

Based on what I've seen the overall performance is limited by the code only using a single core to run the hash, which means the CPU cycle time is a bottleneck.

So a faster single core CPU beats a slower multi-core on a lot of the work I am seeing.

Not sure if that's an issue with the re-indexing, because that might be due to the database code.
