The first 4-5 days of syncing my bitcoin knots node I got to about 70%. Its been about 2-3 weeks now and I am at 78%.
I am running an HDD 5TB drive, which I know is not best, it’s just what I had on hand. I’ve seen other posts previously about a similar slow down after 70%.
I restarted my server and knots several times. No VPN on. Is there anything I can do to speed this up. Internet speed is not the problem either.
Edit: Should I try clicking on the “System Rebuild” option? Might help?
HI
Syncing slows down significantly after 70% because your node is now processing more recent blocks, which are larger and contain more transactions than the early years of the blockchain. Using a 5TB HDD is likely the main bottleneck—HDDs have much slower random read/write speeds compared to SSDs, and this really impacts performance during the later stages of IBD (Initial Block Download), when the node has to verify millions of UTXOs and handle a more complex chainstate.
The biggest improvement you can make is to switch from an HDD to an SSD, as SSDs are much faster for the random read/write operations needed during the initial block download. Additionally, increasing your RAM and raising the dbcache value in your bitcoin.conf will let your node cache more data in memory, which further speeds up syncing—especially if you already have an SSD.
