Handle limit windows 2008

The limit that these versions impose is the highest permitted physical RAM address, not the size of the IO space. For example, drivers could map the "lost" memory regions located above 4 GB and expose this memory as a RAM disk.

The bit version of Testlimit Testlimit Once the commit level reached the size of RAM, the rate of thread creation slowed to a crawl because the system started thrashing, paging out stacks of threads created earlier to make room for the stacks of new threads, and the paging file had to expand.

The results are the same when the —n switch is specified, because the threads have the same initial stack commitment. The number of processes that Windows supports obviously must be less than the number of threads, since each process has one thread and a process itself causes additional resource usage.

If the only cost of a process with respect to resident available memory was the kernel-mode thread stack, Testlimit would have been able to create far more than 8, threads on a 2GB system.

Dividing the amount of resident memory Testlimit used 1. Since a bit kernel stack is 24K, that leaves about K unaccounted for. This acts as a guarantee to the process that no matter what, there will enough physical memory available to hold enough data to satisfy its minimum working set. The remaining roughly 6K is resident available memory charged for additional non-pageable memory allocated to represent a process. A process on bit Windows will use slightly less resident memory because its kernel-mode thread stack is smaller.

Hi — One of our more popular blog articles from January 14, It has been over three years now and the blog article needs a refresh.
