What

Resolves: Logging SDK speed regression #4093

Arrow was default to a Debug build regardless of what CMAKE_BUILD_TYPE was specified.

Baseline:

$ time RERUN=on ./build/rerun_vrs_example sample.vrs
real    0m15.105s
user    0m16.409s
sys     0m2.981s

CMAKE_BUILD_TYPE=RelWithDebInfo

$ time RERUN=on ./build/rerun_vrs_example sample.vrs
real    0m4.659s
user    0m5.259s
sys     0m2.257s

-DARROW_MIMALLOC=ON

$ time RERUN=on ./build/rerun_vrs_example sample.vrs
real    0m3.477s
user    0m5.015s
sys     0m1.291s

Let's make sure this works on Mac & Windows before mergning
I remember disabling jemalloc because of build issues somewhere (don't know which one) and turning it off helped (didn't think much of perf impact at that point ofc :( ). Still opens the question though whether we should use jemalloc over mimalloc or not.

just cpp-test works on Mac

…BUILD_TYPE for debug/release

Wumpf · 2023-10-31T16:19:02Z

oh wow. CRLF strikes again. my settings are broken
edit: fixed

Wumpf

fixed for windows now, didn't run benchmarks though, only made sure build all & tests work

emilk · 2023-10-31T16:30:32Z

tip: there are global git settings you can set regarding CRLF

tip: there are global git settings you can set regarding CRLF

I know, that's the strange thing, I set autocrlf = false on my global .gitconfig and I still got this. Must be something else in VSCode that caused this because changing the endings and commting that worked fine 😕

this makes no sense to me - isn't this casting T to T? Are you sure this is needed?

Yeah it's this weird quirk of C++ where char + char == int

(you know that weird quirk. Not like the others)
Bites me every time!

actually only works with unsigned char, which is also the case I got a warning in (uint8_t)

God damn you C++
