|Your process was too big for physical memory, so it was doing a lot of |swapping to disk. Once you got enough memory you didn't need to swap |and the disk access went away (and the process worked a lot faster) I now see this point made by numerous respondents (sp?) Thanks to all who replied. My confusion was based on the fact that the code in question ran in only 4MB on a VAX, and I forgot the "true" meaning of "reduced instruction set" when I used the code on a 4d35. I tried the gr_osview command while running the code and, if I interpret it correctly, I need at least 18MB to run on the 4d35 (not counting modifed memory pages). Thanks again to all (esp. Scott Dorsey who brought the VAX vs. RISC aspect to light) Stephen J. Scotti ASB, NASA Langley Research Center s.j.scotti@larc.nasa.gov
