* replace rocksdb row cache with larger rdb lru caches - these serve the same purpose but are more efficient because they skips serialization, locking and rocksdb layering * don't append fresh items to cache - this has the effect of evicting the existing items and replacing them with low-value entries that might never be read - during write-heavy periods of processing, the newly-added entries were evicted during the store loop * allow tuning rdb lru size at runtime * add (hidden) option to print lru stats at exit (replacing the compile-time flag) pre: ``` INF 2024-09-03 15:07:01.136+02:00 Imported blocks blockNumber=20012001 blocks=12000 importedSlot=9216851 txs=1837042 mgas=181911.265 bps=11.675 tps=1870.397 mgps=176.819 avgBps=10.288 avgTps=1574.889 avgMGps=155.952 elapsed=19m26s458ms ``` post: ``` INF 2024-09-03 13:54:26.730+02:00 Imported blocks blockNumber=20012001 blocks=12000 importedSlot=9216851 txs=1837042 mgas=181911.265 bps=11.637 tps=1864.384 mgps=176.250 avgBps=11.202 avgTps=1714.920 avgMGps=169.818 elapsed=17m51s211ms ``` 9%:ish import perf improvement on similar mem usage :) |
