Fantom-foundation/go-opera最新发布版本:v1.1.3-rc.5(2023-10-14 20:15:09)
1.1.2-rc.5 is an optimization release. Improvements include batched genesis blocks processing, configurable DBs management, parallel EVM logs search and optimizations in p2p protocol. Depending on hardware, it can achieve approximately ~1.3x improvement for events/blocks processing, ~3x improvement for genesis file processing (except for archive genesis files), ~5x improvement for logs search.
There are two migration options for upgrading to 1.1.2-rc.5:
- Preserving the existing legacy DBs layout:
--db.migration.mode reformat --db.preset legacy-ldb
. This option is instant but will leave out some of the performance improvements for blocks/events processing. - Rebuilding DBs according to a new layout:
--db.migration.mode rebuild --db.preset X
, where X is a selected DBs layout. Migration will take a lot of time - for an NVMe SSD drive, the number of hours would be roughlydatadir size in GB
divided by 50GB/hour
. If the remaining disk space is insufficient to store a copy of largest DB in datadir/chaindata, then the migration will take up to 3 times longer, depending on available disk space.
Flags --db.migration.mode
is required only if datadir isn't migrated yet.
There are 2 options for the new --db.preset
flag:
-
ldb-1
- fastest LevelDB layout (default option). -
pbl-1
- fastest Pebble layout.
Pebble offers slightly better performance and smaller IO utilization on average, especially with extended cache. We don't recommend using Pebble presets for validators nor other mission-critical nodes yet.
