Slow time to load saved solution about postflop-solver HOT 3 CLOSED

I just realized if I use your function, it loads in around 1 second:

let mut game: PostFlopGame = load_data_from_file("test.bin", None).unwrap().0;

I still have the issue of not being able to load files concurrently though.

The reason the load_data_from_file function is faster than your code is probably because the former uses std::io::BufReader. From here on, I will assume a situation where the BufReader is used.

In conclusion, I don't think parallel loading improves performance. I cannot say for sure about the MacBook's SSD performance because it depends on capacity, but assuming a 1 TB or larger capacity SSD, which is the fastest, its read speed is at most 6 GB/s. This maximum speed would not be achievable in a real-world application, so reading 1.8 GB in 1 second is actually fast enough. Parallel execution is not a magic bullet for speed and cannot overcome SSD bottlenecks.

That makes sense. Thank you 🙏
