Here are my timings for sorting a 600 Mb file after giving "sort" one Gigabyte of memory and a very large workspace. It used about 800 Mb of disc workspace and didn't make a dent in the memory. The unsorted file is random order but I also reverse sorted it to be sure that the test is representative.
This test server is nothing special - a 10 year old HP 9000 with HP-UX 11i and slowish 36Gb 10k rpm discs.
Are you sure that you file is only 200 Mb ?
