Webb29 juni 2024 · Using multiple thread-pools or even work-stealing threads such as in crossbeam-utils and rayon would be inefficient and would have a lot of OS overhead. This is why I'm thinking of Tokio: it would likely give me a work-stealing thread-pool and would be able to do a lot of concurrent I/O, yielding control back to the pool whenever I/O blocks.

WebbAdd a Comment. Cocalus • 3 yr. ago. It may not work in your case but the way I dealt with this was to split the IO and rayon parts entirely. So I would load all data using futures::stream::StreamExt::for_each_concurrent to mask the network latency. Then I would process that batch of data with a rayon running under tokio::task::block_in_place ...

WebbTokio is fast, gos runtime is also quite fast. The benchmarks mentioned about async rust being slower are from a bad implementation from someone who had never programed much rust before. You can write any program in any language to be slow. It is unlikely that go would be much faster if it is at all.
