I ran some tests on a 486-66 ASUS S3PG with an NCR53c810 and 16MB of
RAM, pitting Linux 1.3.83 against the FreeBSD 2.2 SNAP CD. Since I
didn't do all the work necessary to perform an accurate comparison
(the compilers were different for example), I'll skip the specific
Byte UNIX Benchmark numbers. However, I did note a few interesting
things:
As Terry noted, the file copy test improved dramatically when
FreeBSD was run in async mode. The resulting performance was
within 2% of Linux.
The execl throughput test was a complete massacre, with Linux more
than an order of magnitude faster. Does anyone familiar with the
internals of exec know why?
I also ran iozone using a 50MB file with 4096 byte records. Terry,
I think your idea of a FreeBSD upgrade for Linux may be coming
true...
FreeBSD on UFS:
2770803 bytes/second for writing the file
3908495 bytes/second for reading the file
Linux on ext2fs:
3220442 bytes/second for writing the file
1950476 bytes/second for reading the file
FreeBSD on ext2fs:
2768517 bytes/second for writing the file
3265638 bytes/second for reading the file
Naturally, Linux on UFS resulted in 0 bytes/second :)
