nothing

found this: http://webserver.cpg.com/reviews/r1/3.4/
nice read, but doesn't answer my question in the slightest.

interesting, tells me nothing.

Found ton's of design discussion and docs from 1999.

I'm wondering where the absolute plethora of documentation you're talking
about might be. It's not on openbsd.org. It's not archived on google. I
guess I could download all 200MB++ of the list since the search function
seems to be out of commission.

I'm sure there's plenty of posts by people saying, "hey I have 100 tunnels
running on my P75 box with 32MB of memory". I just haven't found them
yet.

Simply mentioning that freeswan exists seems to be synonymous with hating
openbsd and therefore prefering freeswan. Fact is that I find linux to be
hard to secure and keep up on why would I want that in a fw/vpn box?

I'm very happy for you. I've been sleeping well for awhile now myself.

Sorry to have "bothered" so badly with my blatently lazy post, Pedro.
Perhaps it will suffice to say that "openbsd's ipsec is probably
blindingly fast".

Thanks for all your help and insight.
