https://issues.dlang.org/show_bug.cgi?id=11531 --- Comment #1 from Jack Stouffer <jack@jackstouffer.com> --- Created attachment 1635 --> https://issues.dlang.org/attachment.cgi?id=1635&action=edit test.d Currently group does not auto-decode, and I have attached a test case which shows that using immutable(ubyte)[] rather than string has a huge performance pessimization being almost 2x slower. -- |

Hmm dmd does not show this performance problem but ldc does $ dmd -O -inline -release test.d && ./test original 5 secs, 355 ms, 103 μs, and 7 hnsecs new 5 secs, 70 ms, 858 μs, and 6 hnsecs $ ldc2 -O5 -release test.d && ./test original 576 ms, 524 μs, and 6 hnsecs new 992 ms, 676 μs, and 6 hnsecs Odd. -- |
