bottleneck. Buy SSD hard drive, or big memories and use memlib option.

I set a 16G disk in memory for windows temporary files and sas data storage,
it is enough for most applications. The speed is amazing, just like flying
compared to other options.
The reason is mentioned by somebody else, SAS is disk based.
SSD is not stable at all according my experiences. Also, SSD's advantage is
reading instead of writing. SAS will generate lots of temproray files.
