StructLinq performance degradation #236

ksysiekj commented 8 months ago

hello, working on some performance improvements in my project and encountered your this project. Also found similar one [NoAlloq] (https://github.com/VictorNicollet/NoAlloq). Ran some benchmarks and turned out that StructLinq is worst when it comes to simple filtering and projecting. My benchmark code and it result could be found here

Can you please advise on what I'm doing wrong?

Hi, I can reproduce your figures. I made some modifications and by example if you transform User in a struct, performances are better.

For the moment, I don't understand why.

@reegeek any update?

Hi, I have no simple solution to improve performance. Moreover, I have less time to work on this project.
