Blockchain synchronisation takes to long about ain HOT 5 CLOSED

Hi @izzycsy
Can you move that issue to the app, please?
This is the wrong place, I think.

Hi @Darkman-Q-Tester
Thanks a lot for posting all your app issues. They are really well prepared, but I think they should be created here (for the future)
https://github.com/DeFiCh/app/issues
In this folder the blockchain source code is handled, not the App.

I'm sorry I was wrong. I apologize.

Hi @izzycsy
I'm sorry, I did not saw the wiki "How to submit issues for DeFi app" before opening the bugs. Please cancel all my bug's because I don't have the logs stored for that so they are worthless. I will recreate them after testing again. I apologize.

I have an educated guess here - CPU usage is limited to 1 CPU only somewhere in defid source code.
So in order to speed up the sync there should be a way to allow using more than 1 CPU.

To add a bit more background, in my case sync is really fast for the first 50% of blocks when there are pretty much no transactions to verify. Disk writes go as high as 50-70 MB/sec but only one logical CPU is utilized.

As sync gets to more recent blocks with more transactions in each of them CPU utilization stays the same (only 1 logical CPU utilized out of many CPUs), but disk writes go to 10-20 MB/sec due to CPU bottleneck.

Yes, that's reward history (enhancedcs). By default it's -acindex-mineonly if you don't need account history don't hesitate to use -acindex-mineonly=0. The app uses -acindex-mineonly to show the tx and rewards history. We are aware of the rewards are too frequent so that increase disk usage
