bitcoin-qt consumes too many io’s #12492

   v0.15.1

   On fully up to date Fedora 27 the thread (using iotop) bitcoin-qt [bitcoin-msghand] consumes far too many io’s making the system slow to respond and nearly unusable as even typing is affected and the cursor frequently locks. This was not observed to cause any issues on Fedora 23.

   After starting bitcoin-qt and when loading is complete (after the splashscreen disappears Issue# 12355) the thread io’s sits near 99% forbitcoin-qt [bitcoin-msghand] for an extended period, until all outgoing connections are made or, until the blockchain is synced, I have not isolated which. During blockchain synchronization, I often only have a few outgoing connections but have a big list of addnode= in my conf file. When I come back later the required number of outgoing connections have been made, the blockchain is synced up to date and, the io’s have dropped to a normal level and, the system is usable normally.

   bitcoin-qt [bitcoin-msghand] io’s should not cause significant usability issues.

   This situation seems much improved after running upgrade again and getting kernel-4.15.4 and Bitcoin Core v0.16rc4. Perhaps it is one or both responsible for the improvement.

   Sounds like this is resolved for you in the latest releases of the kernel and Bitcoin Core.

   I’m going to close this issue for now, since it’s not tracking any actions. Feel free to re-open if you have further issues.
