added 2 new implementations from users who commented on my reddit post as a comparison
2024-07-31 13:58:42 +02:00
25d20169aa
some improvements by reducing the casts, implemented a get_pos function to get position of byte in byteslice by bitmasking... slightly slower
2024-07-31 12:49:16 +02:00
2c23e30fe0
hash stationnames myself for faster HashMap
2024-07-31 09:27:02 +02:00
da72f38e42
don't need own parse_line function
2024-07-29 12:09:05 +02:00
5aa94e67d1
use read_until method instead of custom function because it is faster than mine using the Bytes struct
2024-07-25 15:35:10 +02:00
c6b8273d65
applied clippy
2024-07-25 13:05:53 +02:00

My multi-treaded version is now faster than polars and takes less time to compile. It's a little more complex though
2024-07-25 10:03:37 +02:00
dcaca0cc65
managed to make my solution super fast... but it's also incorrect
2024-07-24 15:19:17 +02:00
16cf4ca2ca
moved from reading String to reading bytes. A little faster, still need to implement for multithreaded solution
2024-07-23 16:30:50 +02:00
b4e3992c65
mostly made output a bit nicer
2024-07-23 13:23:26 +02:00
393f802741
remove the need for mutex by using channels
2024-07-23 13:23:26 +02:00
327fe8564e
use scopes to allow to use mutex without arc
...
apply clippy to my implementations
2024-07-23 13:23:26 +02:00
14d608b209
Fastest yet with scaled integers instead of floats
2024-07-23 13:23:26 +02:00
2f82e8788d
moved rust implementation to /src/main/rust
2024-07-23 13:23:26 +02:00
91adbf4c1c
Actually I just needed to add target-cpu=native to [build] in Cargo.toml, did that and create HashMap with capacity, also added reference implementation (which uses libraries unlike my solution)
2024-07-23 13:23:26 +02:00

The polars solution I saw on reddit a few months ago is also super slow. I'm thinking it might be my macbook
2024-07-23 13:23:26 +02:00
fe1053b74a
Multi threaded works now but it's slower than single threaded...
2024-07-23 13:23:26 +02:00
3ffed9099c
Still broken but it compiles. For some reason lines are not properly being read and only one thread is being run
2024-07-23 13:23:26 +02:00
65df621cf6
use hashbrown instead of std hashmap, no performance improvements
2024-07-23 13:23:26 +02:00
bd83b9bc2c
not working multi threaded solution
