Synchronization is too slow #125

Open osinniy opened 1 year ago

osinniy commented 1 year ago

Dear team,

A few days ago I stopped syncing normally. Log shows slow orphan process. neard log

I have 10-30 peers, some of them are dead, but with any number of peers, I still can't keep up with the network speed. Sometimes synchronization speeds up and blocks are downloaded, but after a while the consensus still gets lost.

Cpu and memory are fine: htop output

I`ve restarted node many times, fully resynced, but nothing helped. I think this can be consensus bug.

My node in West US (Azure) is experiencing the same. Another one feels great in Frankfurt, I’ve migrated validator there for now. I could not correlate this issue with ram/cpu/io/network usage. The only hypothesis left is that location does actually matter, and that is very bad for network decentralization. I am on latest commit fe435d02c5ea497933c89d5e7d1703d9379b7e1f

I`ve migrated to NL and problem seems to be solved.
