Prune Node sync more than 7 hours #3758

Closed noobvie closed 1 year ago

I tried new versin v5.2.0-beta.1 and see that the sync time up to 7 hours or sometimes completely stuck. I tested in all windows/ubunbu machines in differnet continents. I set everything by default.

For version v5.2.0-alpha.2, it only takes 2 hours to have fully sync even only 8 connected peers.

Regarding your logs you lost peers several times, can be a reason. How much peers you had at all? Are you using default grin-server.toml config? If not, please share your custom config too.

noobvie commented 1 year ago

I have put everything by default, Just ./grin and run. The issue did not happen to old version. You did not have any sync issue in new version?

ardocrat commented 1 year ago

Problem is you have lost peers, maybe with PIBD_HIST capabilities who can provide PIBD segments during initial byte download. I think it will be fixed when we have more nodes updated to last version with support of PIBD.

This happened once for me, after initial PIBD step I have lost all peers, recovered slowly in next 5 minutes.

Ok, let me try to update all of my nodes to latest version and see
