Web application with probably 250,000 lines of perl that's been running on CentOS 5 for well over 5 years. Just got it and the ~200 CPAN modules it requires up and running on CentOS 7.
Response times instantly halved. Not sure yet whether that's perl 5.8 → 5.16, kernel 2.6.18 → 3.10.0, mongodb 2.6 → 3.2 or what but I'll take it.
Well that was fun.
