I don't really want to use the suggested -O2 -m486 however, so I think I'll add -pipe. I don't have the time to do another make world to compare however.. I've got 32 MB or RAM - is this considered enough? SCSI - of course: NCR 810, but the disk (CONNER CFP1060S 1.05GB 2035) is rather slow. CPU is a 150MHz pentium pro, 128-bit interleaved RAM (STREAM says about 94MB/s..). Any idea how much faster -pipe generally speeds up the compilation? I'm assuming I might need more RAM for the PIPES to talk though.. I'll be up to 48MB soon, then I'll be happy :-) Thanks, -Mark > > -- > ]] Mike Smith, Software Engineer msmith@gsoft.com.au [[ > ]] Genesis Software genesis@gsoft.com.au [[ > ]] High-speed data acquisition and (GSM mobile) 0411-222-496 [[ > ]] realtime instrument control.
