Yes, it is quite busy and does IO back and forth to disk often. In analysis, on Mac OS X, I find it's consumption of real RAM tops out at about 1.5 Gbytes, no matter what I throw at it (measured on a G5/2GhzDP system with 3G of installed RAM). Virtual memory, however, can go quite a bit higher. I run it on my desktop system with about 80G free on the startup drive and on the laptop with about 20 G free at present. When I've allowed the latter to drop down below 10G, performance suffers noticeably. G -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net
