June 15, 2010 Idea: Compilation benchmarks for D publicity | ||||
---|---|---|---|---|
| ||||
This post: http://www.realworldtech.com/forums/index.cfm?action=detail&id=110745&threadid=110549&roomid=2 ...has made me realize that it would be very good for D if we had some good D-vs-C++ *compilation* benchmarks. Something template-heavy, and preferably real-world. Or maybe something specifically meta-programming-heavy that has four versions: - C++ template metaprogramming without precompiled headers - C++ template metaprogramming with precompiled headers - D2 template metaprogramming - D2 CTFE (while falling back on templates, of course, for anything that can't be done in CTFE). And, of course, have results for: - DMD - LDC (or maybe not, it's still D1-only, isn't it?) - GDC, if it's gotten good enough yet (don't know, haven't been following it) - DMC (for apples-to-apples with DMD) - GCC (to demonstrate a typical case, since GCC is so popular) - GCC using the Gold linker (since it's the new poster boy for speedy C++ linking) - LLVM's C++ compiler (I assume it has one, right?). And, obviously, do a "clean" between each run...erm...I mean, between each compile. Could be helpful for demonstrating things like just how much faster D compiles, and how with D it doesn't really matter if templates are slower than not using templates, and, of course, for sanity-checking all of our beliefs about D compilation speed. Also would probably be good to read and heed the advice in here: http://www.zedshaw.com/essays/programmer_stats.html ("Programmers Need To Learn Statistics Or I Will Kill Them All" <-- I love the article's name :) ) I don't have time to attempt this. Plus I'd have no idea what project to look for on the C++ side, and I'm completely out of practice on C++. Any takers? ------------------------------- Not sent from an iPhone. |

Adam already posted some encouraging ad-hoc results, but a real benchmark would be a great thing to have. Would probably be difficult to design/run though. But if the overhead from using PHP really does rival or surpass the overhead from using plain vanilla CGI, then a reliable benchmark could clear up the long-held misconceptions about CGI, and give anyone who's server allows custom CGI an extra reason to go from PHP to D. |
