[Mono-dev] can mono run under AIX 4.3, 5.2
Dear lists, I hope my C# web application can run under AIX 6000. The OS versions of AIX6000 are 4.3, 5.2. Who know if there is mono binary release for aix? tks zhu __ Do You Yahoo!? Tired of spam?

Re: [Mono-dev] how to improve mono performance
(1) I feel a little disappointed at the comparsion results. I think we should not only prove we can do this but we can do even better. The performance fact is very essential for production applications. I hope the mono community can improve performance of mono largely. Then mono will be depoyed in many real apps.

I just got 10% faster than that compiled by mono mcs.

I would suggest benchmarking a ported application rather than these micro measurements. If you want to do such measurements, I would recommend something more relevant to your application (database accesses? the asp.net pipeline?)

Re: [Mono-dev] how to improve mono performance
I very agree with you. The right direction to improve performance should be from : - class libraries - compiler outputs - JIT I don't think we put emphasis on apps. Because we have the same source, but the running results are so different using linux+mono and msft .net. I insist that performance is the key factor for key applications. For example, we now have one enterprise web query application. Every day between 8:30AM and 12:00AM, it serve about 2 requests. Now we use one P4 2.6G PC Server with 512M DDR running Windows 2003 Server, it works well. If we port it to Linux + Mono, we must upgrade the hardware to meet the same workload. tks zhu --- Atsushi Eno [EMAIL PROTECTED] wrote: zhu shi song wrote: (1) I feel a little disappointed at the comparsion results.

We have spent so much effort on it, we shouldn't let it be reference implementation just for lab. I agree that performance improvements are impressive, but against your expectation mono is already used in practice, including softwares and individual solutions: http://www.mono-project.com/Software http://www.osnews.com/story.php?news_id=10714 (2) when I use msft's csc to compile compare.cs, then I run under linux+mono. I just got 10% faster than that compiled by mono mcs. So maybe mono's jit is not so good as msft's. Wrong assumption. There are three factors in mono to affect on performance: - class libraries - compiler outputs - JIT The most effective optimizations could be done at class libraries (which could be usually done with a few lines of changes on a few critical paths), where many hot users among users turned into hackers and posting several patches here (and there). Actual analysis and thoughts on which affects on performance are welcome (like what Ben wrote). It would be awesome if you try mono --profile (or heap-buddy in our svn repository) to count individual performance, find out where the code is specially slow, and optimize the sources. Even a line of change could result in more than 200% performance boost in some code areas (I often got such hits in DOM/XSLT areas).

[Mono-dev] mono string internal representation problem
Dear sir, I found that string internal representation in mono is different from in ms VS.Net. For example, In Mono: --- ldstr 12\u795D\u798F Mono uses ucs-2BE as default string internal representation In MS: --- ldstr 12\u5D79\u8F79 MS uses ucs-2LE as default string internal representation I think the problem can cause System.Text.Encoding doesn't work correctly. So How to handle the compatible problem? tks zhu __ Yahoo!

[Mono-dev] how to improve mono performance
Dear lists,
I've got one test example and tested it using linux
mono and windows .NET on the same machine. The
results showed that the performance of linux mono is
much bad than windows .NET.
Linux Mono:
ArrayList strings test.3311 ms
StringBuilder test.4008 ms
Integer Floating ADD.15145 ms
Exception test.621 ms
Reflection and recursion...9421 ms
Windows .Net:
ArrayList strings test.1109 ms
StringBuilder test.1437 ms
Integer Floating ADD.2734 ms
Exception test.4046 ms
Reflection and recursion...5843 ms
Machine configuration:
RAM: 512M DDR
CPU: Intel C4 2.0G
OS:
Windows 2003 Server .NET 1.1 Framework
Fedora Core 4 with mono compiled from svn
Now I try to port my aspx web application to linux
mono from windows 2003 .net framework. But regarding
of performance, I wonder whether it is deserved.
Maybe I lack some tips to improve linux mono
performance. If someone knows pls help me.
