That's quite slow compared to what I get. On my 2x133MHz Pentium machine (-j8, src/obj on separate (src SCSI, obj IDE, neither is particularly fast) disks, -pipe, noatime, obj async): -------------------------------------------------------------- make world started on Sun Nov 9 16:01:56 EET 1997 -------------------------------------------------------------- ... -------------------------------------------------------------- make world completed on Sun Nov 9 19:29:20 EET 1997 -------------------------------------------------------------- The source tree had been cvsupped a few hours earlier. I guess the >7h and >5h results are with a SMP kernel but without -jX? Before I had SMP working properly, I made world on the same machine with a single CPU kernel, no -pipe, no noatime or async, obj and src on the same disk. It took just under 6h. An SMP kernel does seem to slow some things down a bit.
