execution 7/15 slow

[directsyndikat]

Using:
./build/bin/erigon
--chain=bor-mainnet
--bor.heimdall=https://heimdall-api.polygon.technology/
--internalcl
--prune=hrtc --torrent.download.rate=128mb

Expected behaviour:
Prune till the latest 90.000 blocks.

Actual behaviour:

Questions:
Does it require to execute all blocks till latest block and prune after?
Is there a flag i can use to speed this up?
Is this normal behaviour?

update:

It seems like its barely using any cores / memory. I tried adding the following flags without result:
--db.read.concurrency=1024
--rpc.batch.concurrency=18

Polygon is very-very big.

• or throw a lot of good hardware RAM, nvme, etc... and it still will take weeks.
• or switch to Erigon3 https://github.com/erigontech/erigon?tab=readme-ov-file#erigon3-users-guide

Thanks, i just switched to Erigon3, this issue can be closed.

Im currently running Erigon3, upgraded my hardware.
Running on 256GB RAM, 80 arm64 cores NVME but it seems its barely using resources.
About 2% of total CPUis being used, it looks like its using 1 core and 24GB RAM being used while executing.
Any idea how to use more of its CPU / RAM?

1. We released new files of E3 polygon (will do alpha3 soon). Please update and re-sync.
2. It using all RAM: https://github.com/erigontech/erigon?tab=readme-ov-file#htop-shows-incorrect-memory-usage
3. SNAPSHOT_MADV_RND=false may allow to use more read-IO. But probably you don't need.
4. Let it sync 1 day - if will have problems - then show logs.
