Unfortunately, modern Operating Systems have introduced a new source of latency, the kernel / userland division. Application code runs in userland, which must transition to the kernel 
in order to perform any hardware operation.  This transition adds quite a lot of latency, which varies between different OSes, motherboards and revisions thereof, etcetera.  A Windows 
XP system can see an additional 7µs per transaction; a modern computer might see 3µs or less.  Any transaction from the kernel itself, however, avoids this additional overhead. 

Real-time operating systems will enable the highest transaction rates possible, all the way up to the hardware limits. 

The latest information can always be found on the product page on the website.  Here are some useful links:
