P.S. Can anyone post some benchmark comparing gitweb deployed under
mod_perl as compared to deployed as CGI script? Does kernel.org use
mod_perl, or CGI version of gitweb?

CGI version of gitweb.

But again, mod_perl vs. CGI isn't the issue.

IO is the issue, and the CGI startup of Perl is quite IO & CPU
intensive. Even if the caching headers, thundering herds and planet
collisions are resolved, I don't think you'll ever be happy with IO
and CPU load on kernel.org running gitweb as CGI.

I/O - nonexistent; that stuff will be in memory.

CPU - we have more CPU than you can shake a stick at, and it's 95+% idle.

*NOT AN ISSUE*.
