Hi! I need to iterate through *all* TON transactions in order to build some indexes and statistics. I have an archive node running locally and use toncenter/ton-indexer (Python/libton) to crawl that but it's pretty slow (processes about 3500 blocks per hour) with the liteserver connection throwing a lot of errors (timeouts mostly). My server appears I/O bound (maxes out at about 300MB/sec). Any ideas to improve that? What would be the fastest way to iterate over all txns from Python? Also, is there a list of public archive nodes so that I could distribute the queries?
