Both use gcc 3.2. The desktop pentium III is very old. Slow ram/bus may be the reason. Or this may be the fastest a pentium iii 1 MHz can perform?. Large RAM don't help pentium III. It doesn't need them here. Large RAM should help Cursoe a lot. CMS should use those RAM as traslation cache and put the entire processes (make, gcc, as) in it. I guess 17.x min kernel compile time result from CMS still taking time interpreting x86 code (because it decide to do so to conserve translation cache space?). I wish the linux kernel could hint CMS to do a better job, if possible, like when to interpret, translate or fully optimize and save-to-disk for later use.
