A small test showed very disapointing result. (This is not a desktop performace test, only I play with it) I tried to compare my Ultra 5 ( 333MHz single CPU / ATA66 IDE / 256 MB ) with Celeron 600 MHz box ( ATA 66, 256MB memory). My test is to calculate the complecity of Linux kernel code. (command line: # sloccount /usr/src/linux-sparc-2.4.27/ ) On U5 it takes325 seconds, on Celeron it takes 257 seconds. They both take almost same amount of kernel time, but U5 takes 210 seconds user time, while Celeron only takes 76 seconds. To perform this task, Celeron used 79% of total time compare to U5. So I think perhaps U5 does not perform better than Celeron 500MHz. This way, I can hardly expect dual 300MHz would overperform Pentium 1G, especially dual CPU (IMHO) does not help much with desktop thanks to that only a few desktop applications use more than one process... Perhaps I am wrong in this small test? -- gentoo-sparc@g.o mailing list
