2) Windows has a 3GB feature. This might provide for a bit more virtual address space. Note, this applies to 32-bit Windows. There may be an analog to this on 64-bit Windows for 32-bit applications. Edit: from https://techcommunity.microsoft.com/t5/ask-the-performance-team/memor...
Before Windows Embedded CE 6.0, there was a limit of 32 processes, and a 32 MB limit on virtual memory (VM) for each process. Also, all of the processes shared the same 4 GB address space. For CE 6.0, the kernel process resides in the upper 2 GB of the 4-GB (32-bit) virtual ...
