Hi Michael,


I tried to compile mod_managed on centos 5.2/32bit, mono 1.2.4 and
mono-devel files. I get this error:

For let's say you use F# and download some HTML and parse it, then read it back to the user. The parsing is probably going to be so fast that it your performance is totally dominated by the downloading of the HTML. So the fact that it takes, say, 1ms in F# versus 10ms in "other language" is probably not relevant.
