Recent / upcoming releases of Tcl include support for poll and epoll to
get past the limits of select. Is this going to conflict with anything
in naviserver?

Ok, thickening the plot a little bit - if I enable adp parsing and serve
the exact same file as adp, the delay on localhost goes away. So,
something weird with plain file handling on loopback?

I am running a test using ab against a local naviserver instance with a

I was just considering this exact same thing, and it appears the answer
is no. You should be able to serve multiple vhosts on different ip

As part of porting a feature to naviserver, I'm trying to understand all

There's no builtin way I know of to define a default extension. I would
