Someone posted the question on StackOverflow and it got closed as "not constructive". Is there a way to browse the "not constructive" questions on SO? They seem to be all the best ones.

Ref: http://stackoverflow.com/questions/6916011/how-do-i-get-windows-to-go-as-fast-as-linux-for-compiling-c http://stackoverflow.com/questions/6916011/how-do-i-get-wind... (By the author) Top Answer: Unless a hardcore windows systems hacker comes along, you're not going to get more than partisan comments (which I won't do) and speculation (which is what I'm going to try). 1. File system - You should try the same operations (including the dir) on the same filesystem. I came across this which benchmarks a few filesystems for various parameters. 2. Caching. I one tried to run a compilation on Linux on a ramdisk and found that it was slower than running it on disk thanks to the way the kernel takes care of caching. This is a solid selling point for Linux and might be the reason why the performance is so different. 3. Bad dependency specifications on windows. Maybe the chromium dependency specifications for Windows are not as correct as for Linux. This might result in unnecessary compilations when you make a small change. You might be able to validate this using the same compiler toolchain on Windows.

  Why should he run the ls command on ntfs rather then a native file system? In all it was a "windows vs linux" test and not a fileystem test. Testing the same filesystem wouldn't make sense here

    Presumably to find out whether the difference lies with the filesystem or somewhere else? If Linux is still much faster, even with the same filesystem, you have eliminated one variable.

      Doing some profiling and system/kernel level analysis would be much saner, imo. What's the sense in measuring how some non-native filesystem behaves? In the end you'll be benchmarking how good is fuse-ntfs vs. in-kernel-ext4 and figuring it's slower... I say, profile some code and see how much time is spent in filesystem calls.

      But then you'd be comparing NTFS implementations. The codebases are completely diffrent.

Well, this article seems to be asking "why is the Windows file system so slow?" and generally complaining. A better name for the article might be "Windows FS performance sucks" or similarly polemical title. There are parts of Windows that are implemented just the same as Linux, and parts that are faster. Some parts are slower, notably the file system. But there's more to Windows than just the file system. So, I'd say that's why it's not constructive.

  Well that's the question isn't it? Is it just the filesystem, or is the speed of CL.EXE an issue too? What about the VS build system? It sounds like you simply don't know enough about the issue to judge whether it's constructive.

Interesting. I wonder how many "Linux-bashing threads" (that contained valid questions which made perfect sense) were closed as not constructive.

  No need to invent a new conspiracy - closing and reopening happens regularly and for a lot of reasons/subjects. Just - add a vote to reopen it, if you feel that the question is relevant. I just did.

    Plus stackexchange has so many different subsites, the odds are any given question is off topic for where it was posted nowadays.

http://data.stackexchange.com/ http://data.stackexchange.com/ It's an online SQL tool for analyzing the stackoverflow data dump (last update was Sept 2011; they're quarterly http://blog.stackoverflow.com/category/cc-wiki-dump/ http://blog.stackoverflow.com/category/cc-wiki-dump/). It's very cool, but curiously hard to find. There's a "[data-explorer]" tag at meta.stackoverflow: http://meta.stackoverflow.com/questions/tagged/data-explorer http://meta.stackoverflow.com/questions/tagged/data-explorer The PostHistory table probably records why posts were closed.

closed questions are still there. Only the deleted ones are gone ( but accessible to those with more than 10k reputation)
