Benchmark ULString #44

Closed SupinePandora43 closed 2 years ago

SupinePandora43 commented 2 years ago

Benchmarks

Marshal.AllocHGlobal and Encoding.GetBytes
Cashed Marshal.AllocHGlobal and Encoding.GetBytes
Marshal.StrToCoTaskMem
stackalloc and Encoding.GetBytes
Ultralight.ulCreateString

Results

:P
Faster than run-time heap allocation
No
Same as Cached memory
Slow on short lengths (0-1) fast in all other cases.

Verdict

[x] Use ulCreateString16 for managed->native calls
don't use if/else size checks because they will probably lower performance (correct me in future)

Pros

blazingly fast

Cons

slower on nano lengths (0-16~ bytes)
