LOL. Delayed a few months.

What's there to laugh about.  Bitshares has delayed many features it promised....

Many features that haven't been implemented by anyone. What's there to laugh about is people adore when Bitcoin implements some features and despise other projects that have those exact same features. That's what there's to laugh about. The irony of bitcoin having a great libertarian spirit behind it yet, their community is closed like the same banks they hate.

Speedup of --rebuild-index is insignificant on my system, around 5%. Possibly more on an SSD. The indexing is heavy on IO, so not much speedup to be expected here.

Speedup of wallet_rescan_blockchain is 4% for the mixed implementation and 25% for pure libsecp256k1.

Note that block/transaction signature validation is skipped until after the most recent checkpoint, otherwise IO may not necessarily dominate.

But the main part that slows sync is HDD not CPU. The software could also use more RAM that is left unused.

Sorry it already uses too much RAM lol

We are working to reduce RAM and CPU.

Very glad to see you come back to the most critical topic.

Well, for me when syncing less than 100 hours left, it takes only 1GB of RAM(2GB unused), but uses HDD heavily.

On my ubuntu installations I always run out of 2 GB ram.. even after sync and restarting.. maybe jus tmemory leak in latest release... and my delegate always runs out i had to create a 4 gb swap file and that gets half used but then i start to miss blocks because its slow.. so i just restart it once eveyr few weeks
