05:01 < kcalvinalvin> So my new beefy computer was able to sync up to tip on mainnet in a couple of hours. ttldb is 60GB, proofdata is 451GB, the forest is 8.1GB
05:02 < kcalvinalvin> hmmm now I really wanna work on the "save proof only for odd blocks" thingy...

08:44 < adiabat> kcalvinalvin: wait so this is utreexo current master?  huh
08:45 < adiabat> so really the only problem was the disk i/o... and google servers have horrible disks
08:46 < adiabat> so could just have forest in ram and probably keep ttl db in ram, then don't need disk io / ssd... but need 16GB or 32GB of ram
09:01 < dergoegge> i actually ran into some trouble but i was using an external ssd so maybe thats why
09:01 < dergoegge> when quiting it reached the 60sec timeout
09:02 < dergoegge> i have a pprof trace, i will add a comment to #207
09:03 < dergoegge> there is a lot of time spent on the cow forest commit
09:05 < dergoegge> hm looks like i can't attach the pprof file on a github comment
09:06 < dergoegge> also even with cow it was using ~10GB of ram
09:10 < kcalvinalvin> dergoegge ok some tweaking to do with cow...
09:10 < kcalvinalvin> adiabat yea this is on current master
09:12 < dergoegge> kcalvinalvin: all the commit time comes from flushing the cache, so a different cache strategy should already improve this by a lot. although when quitting you will have to flush it all...
09:23 < kcalvinalvin> ok yeah I'll take a looksie
09:23 < kcalvinalvin> adjusting the treeBlocks and treeTables might also hlep
