描述

Hi,

This has been going on for a long time but geth takes longer and longer to start up. Currently using the pre-compiled 1.8.10 on Linux 64-bit. Pretty beefy machine with 128GB of RAM, NVMe storage, 3 GHz Xeon w/ 8 cores / 16 threads.

My best guess is it's because we have a lot of keys since it's for a wallet provider.

Quick example from today showing timestamps between these 2 lines of geth output:

INFO [06-04|04:26:23] Maximum peer count ETH=25 LES=0 total=25 INFO [06-04|05:38:10] Starting peer-to-peer node instance=Geth/v1.8.10-stable-eae63c51/linux-amd64/go1.10.

研究方向
Investigate the keystore loading process in go ethereum, particularly in accounts/keystore/keystore.go. Profile startup using Go's pprof to identify bottlenecks. Explore options like parallelizing key decryption or lazy loading to reduce startup time with many keys.
