I recall a message in misc (which I am not able to find on the archives)
about someone posting here the results of his research on optimizing and
improving OpenBSD overall performance (fs, network, etc).

Among the links he posted on his comprehensive compilation, he sent
tuning-openbsd.ps.

I remember one reply of a developer stating that some of those tuning
measures are not needed anymore as OpenBSD has grown quite a bit since that
time. Which are the recommended -always working- directions, then, to tune a
system for its particular needs?

My point is we all have to be careful and not follow guides or try values on
sysctls blindly (although experimenting is welcome and healthy) as we can
harm more than benefit we can get. Still, some enviroments will need
adjustment to push much more traffic than GENERIC can, and this is a really
hard task to accomplish unless you are a @henning or @claudio :)
