It will build version 1.0 of lmbench, which seems to be the version refered to most often. I can send you a lmbench-1.1 port, which has been waiting to be commited to the -current tree for a few months, now ... Another good test might be Bonnie (also found as a port in the same directory on FreeBSD). There is also a Byte Bench port, but it does not give useful results in most tests. The problem is, that there are many tests that depend on config options, and for example on whether static or dynamic linking is used for some system commands. [The Linux Byte Benchmark site (at www.silkroad.com) offers pre-compiled Linux binaries, which give up to twice as good results as building from sources with no hand-tweaking on a current Linux-ELF system! (They put statically linked versions of some commands into the benchmark, which will be used instead of the system commands in some tests. This is highly bogus, it does not test system performance as is claimed, but performance of those benchmark components. That makes it even less useful than typical micro-benchmarks, which typically let you know what meaningless metric you measured :) ] If you have any trouble locating the FreeBSD-ports, just try www.freebsd.org or its Australien mirror www.au.freebsd.org (does it exist ?). It offers to download ports and packages. You want the port, and will be able to build Linux versions from the sources typically, since they have not been modified for FreeBSD. Regards, STefan
