The only perf advantage to running IIS on 64bit vevrsus 32-bit is to allow access to a much larger memory address space. If you are doing normal ASPX page processing, then it’s likely you don’t need to address more than 4gb from any single process. Suppose you run in 32-bit mode with a web-garden with … Read more
If you’re shell is running on .NET 4.0 (PowerShell 3.0): PS> [Environment]::Is64BitProcess True
No. The C# specification rigidly defines that int is an alias for System.Int32 with exactly 32 bits. Changing this would be a major breaking change.
Running Kubuntu 13.10 (x64) and I used lib32z1, which fixed it for me. sudo apt-get install lib32z1
That message isn’t actually an error – it’s just a warning that the file in question isn’t of the right architecture (e.g. 32-bit vs 64-bit, wrong CPU architecture). The linker will keep looking for a library of the right type. Of course, if you’re also getting an error along the lines of can’t find lPI-Http … Read more
If you’re using .NET 4.0, it’s a one-liner for the current process: Environment.Is64BitProcess Reference: Environment.Is64BitProcess Property (MSDN)
If you have a large array of numbers, then go with the smallest size that works. It will be more efficient to work with an array of 16 bit shorts than 32 bit ints since you get twice the cache density. The cost of any sign extension the CPU has to do to work with … Read more
QEMU and binfmt support light the way 🙂 https://github.com/microsoft/wsl/issues/2468#issuecomment-374904520 After reading that the WSLInterop between WSL and Windows processes used binfmt, I was tinkering with QEMU to try some ARM development, and incidentally discovered how to get 32-bit support working. Edit: requires “Fall Creators Update”, 1709, build 16299 or newer Install qemu and binfmt config: … Read more
The JVM architecture in use can be retrieved using the “os.arch” property: System.getProperty(“os.arch”); The “os” part seems to be a bit of a misnomer, or perhaps the original designers did not expect JVMs to be running on architectures they weren’t written for. Return values seem to be inconsistent. The NetBeans Installer team are tackling the … Read more
