Hi Could I ask you about the following.

option NMBCLUSTERS="8192"
option BUFCACHEPERCENT=45
option NKMEMCLUSTERS=0x4000

I keep looking in the archive for more information and I only find a bit of
stuff on O'reilly sites.

The option BUFCACHEPERCENT=45 is recommended by O'Reilly and I see in some
place there is discussion that said it is good and some that said it is bad.
But neither provide explications as to why in either way, other then more
cache help and some said the system is not design to support more cache and
will actually be affected adversely and be slower.

I have been researching this for a while and I can't be sure either way. I
run a system for about 2 months with the 45% cache and didn't have problem,
but it wasn't in heavy use.

I would love to know from a developer if possible if the cache option and
the other two helps or not on a system that would be heavy use with 2Gb of
RAM already in there.

One thing that I sure found was that

option MAX_KMAPENT=0x1000

is really not good to use but no explications are provided.

I guess I am trying to understand the why of either side and I am without
success so far.

If you think it would be worth providing some explications, I would love it.
I also understand that time is rare and I may not get any answer to this
question and that would be fine as well.

I am trying to understand it right, but I can't dig real good reason to use
or not to use it.

Any one out there could put some light on this for me?

Many thanks for any answers as small they would be.

Daniel
