[Mono-dev] String class speed improvements

[marek safar]

Hello,

Here are some figures which illustrates the speed up. I ran
enclosed C# micro benchmark with following results.

MS .NET 1.1

00:00:01.0941420
00:00:00.9534666
00:00:02.0476086
00:00:02.0788698

MS .NET 2.0

00:00:01.2660786
00:00:00.9378360
00:00:00.9847278
00:00:05.6113854

Mono SVN HEAD

00:00:02.2820000
00:00:02.0790000
00:00:04.2360000
00:00:04.5800000

Mono patch applied

00:00:01.0290000
00:00:00.9510000
00:00:01.0440000
00:00:04.6140000

You can get even better figures when you make the string longer.
Also the figures are not 100% accurate but I think they illustrate
the speed up.

Regards,
Marek
