I guess you mean the cgi-fcgi/spawn-cgi utilities. I removed them,
because I thought that they are a little bit too specific and not
really mathopd related. They are still available at [1], maybe I
should add them again.

ok, I can do that, though it's not a big issue to compile mathopd
against dietlibc, it works without patching.

hmm, that's a good question. The main advantage is surely that the
binary is statically linked and thus depends on nothing. It should
run on every Linux distribution if you have an i586 or better cpu.
And that's the main reason, why I put the link to the binary into
the wiki.
The other advantage is the very small memory footprint of dietlibc
binaries. With NumConnections = 1 and default values for the
buffers I got the following:
VSZ RSZ
-----------------------
glibc 1732K 648K
dietlibc 256K 140K
But that's not important with mathopd, because most of the memory
goes into the buffers if you have a usable setup.
Another point is overall performance, here is dietlibc ahead too.
A short test with apache's ab and a static web page of around 2k
with 10 concurrency connections gave me 2000 to 2600 requests per
second, which is a nice improvement. But ab is only a test ....
