R2 or newer preleases). It affects all file copies performed in the Windows Explorer or even with the simple CMD line ? Simply Windows fixes absolutely NO limit to the data it will fill up in cache when reading the source files, that will then be written in a background kernel thread. All files to copy (and their data) are simply queued without limitation. Windows starts paging in/out incredibly with conflicting interests between filling the memory cache (for the accumulated pending I/O and their data block) and.

I/O. And this affects the WHOLE system, all processes (UI, services..). It is incredible but Windows cannot fix any limit a process can use to fill the filesystem data caches. Windows should have quotas per process and should be able to monitor the performance : when performance goes so slow, it makes absolutely NO SENSE for. Windows should suspend the process as long as it's pending I/O are not completed to reuse some memory . Note that this also affects ANY application using standard file I/O (because I/O caches are enabled by default everywhere).

If an active.

Filesystem caches are supposed to enhance the performance, but here they are the cause of EXTREMELY SEVERE degradation.
With junctions or symbolic link directories the default behaviour during smartcopy is as follows: By closely looking at the above picture one can find three different.
