Slow node sync with non-pruned snapshot #534

Closed nebojsa-ristovic closed 8 months ago

nebojsa-ristovic commented 8 months ago

Hi,

I started archive node from non-pruned snapshot but sync speed is lower than network block rate - looks like my node will never reach the sync. Flags I use are: --db.preset ldb-1 (as your documentation suggested) --db.migration.mode reformat (since I wasn't able to start node without this flag)

My questions are:

  1. Will you update newer snapshot since current one is almost 2 months old?
  2. Are there any ways to speed up node sync except from cache increase (currently use 16Gb of cache)?

Hi @nebojsa-ristovic , That snapshot was built from a node running with --db.preset ldb-1. You don't need to specify --db.migration.mode reformat.

For trouble shooting syncing issue, this guide may help: https://docs.fantom.foundation/node/troubleshooting#id-4.2-slow-syncing

Hi @quan8, node wasn't able to start without --db.migration.mode flag. But anyway, we are almost done syncing, so my questions are stale.

Thanks for your answer anyway.
