Hi, I was wondering whether it was common knowledge or whether anyone else has noticed how much faster it is to compile things on MandrakePPC over an Intel machine ? For example: 500 Mhz 1Mb L2 Cache, 384Mb RAM Wallstreet Powerlogix G3 upgrade, g++ 2.95 ~3mins Dual 933 MHz Pentium 3, 1Gb RAM , g++ 3.2.1 2.25 Hrs
This is on a ~ 1Mb file that I was trying to compile for my research without ANY optimisation options at all. The file was generated by some other code and consists entirely of statements like -1/3*sin(a+b+c)+2*sin(a-b+c). I discovered this by accident trying to do some work on my laptop at home over Xmas; I thought it would be fun to try several of these huge object files out on my laptop when they take so long on the machines at work. I have some other files to compile that take >24 hrs w/ >900Mb RAM + >10Mb stacksize in the office. I could imagine a factor of 2-3 difference, but to have around 100 including the processor speeds was _very_ surprising. Does anyone have any experience to compare to ? Thanks, Q. I hope you still have a job, Stew!
