If with "servers" you meant also web application servers, it's plenty of them written in Perl.
Amazon.com (i.e. the biggest store ever seen on the web) is written in Perl: is it enough for the chief deprecator? Look at:
http://www.masonhq.com/?AmazonDotCom
Other poular sites written in Perl are: slashdot, AvantGo, DynDNS.org, Salon.com, TechWeb, just to name a few.
As for
Perl reads in its source code directly (rather than a bytecoded compiled version), as the so-called C++ programmer said, you can inform him that Perl source code can be compiled into bytecode as well (and also translated into C code, if you like.)
Furthermore, Perl permits even to inline code written in C, C++, Java, Basic, Python and a number of other programming languages.
