I've moved from Linux to OpenBSD on my router. But the performance of this
BSD box is now much less than the linux was. I've recompiled the kernel but
there's no improvement. When starting f.ex. *X i have to wait about 40
to get it up. On linux box it was immediately.
Hardware configuration of this router is: 486 DX2 66Hhz with 16 MB RAM.

Anyone knows why ?

Because Linux uses a asyncronous filing system. Check the faq for a
complete description.

You might be able to tweak a bit more performance with softupdates and
by increasing the filesystem buffer size when you recompile your
kernel.  The FS still may not be as fast as the async system of Linux,
but it is much safer in event of a power outage if any of your data is
important.

I  ``upgraded'' one  of my  machines from  a trusty  P-60 to  a 266MHz
machine --  it runs  *much* slower than  the P-60.  I'm  convinced (?)
it's a hardware issue with  the hd controller (I'll skip the reasoning
as it  doesn't hold *that* much  water...just a hunch).   There are no
errors/conflicts reported.

I'm not  saying that  this is  what's wrong with  your machine,  but I
think these may be cases when it's appropriate to post dmesg?
