I hope that making this meeting public will make @golang team life easier because feedback loop will be shorter with more eyes on 1 thing.

Changing one character wildly improved our application's performance
Sometimes the only thing standing between your application and 3x better performance is a letter or two.

User Zik have combined and benchmarked @bboreham patches related to the #golang regexp package and...results are astonishing! Well, if all these patches will be merged in 1.19 we can get 30-40% better perf! https://github.com/golang/go/issues/26623#issuecommentโฆ

Nice patch for #golang bigint:
math/big: make NewInt inlineable and zero allocation
Mark the assembly routines as not escaping their arguments.

SIMD has the potential to greatly increase performance of a lot of data processing applications. Since #35307 was closed with the remark We agree that there is an opportunity here, but we don't...

Go generics are not bad
When programming, we often need to write โgenericโ functions where the exact data type is not important. For example, you might want to write a simple function that sums up numbers. Go lacked this notion until recently, but it was recently added (as of version 1.18). So I took it out for a spin. In Java, generics work well enough as long as you need โgenericโ containers (arrays, maps), and as long as stick with functional idioms. But Java will not let me code the way I would prefer. Here is how I would write a function that sums up numbers: int sum(int[] v) { int summer = 0; for(int k = 0; k < v.length; k++) { summer += v[k]; } return summer; } What if I need to support various number types? Then I would like to write the following generic function, but Java wonโt let me. // this Java code won't compile static T sum(T[] v) { T summer = 0; for(int k = 0; k < v.length; k++) { summer += v[k]; }โฆ
