Challenges of compiling PHP and keeping early gains

There's actually a not-too-terrible talk going over some of the challenges of compiling PHP, and how initial promising gains turn out to be very difficult (as OP said) to maintain as you try to encompass the full language. Some great examples of disappointments and challenges! [this video]

Talk on ahead-of-time PHP compilation arguing AOT may beat JIT

Read the full comment

I think its importend to ask everything in these threads. I often find intressting questions answer in these threads (on reddit too). For JIT fans I recomend online-stalking of Mike Pall, here on Hacker News and on reddit. Well I think if you have a task like that a team should look into what other people where doing. Self, LuaJit, parrot, some smalltalk systems, strongtalk where all allready done or on the way in 2008. In a talk about phc ( [this video] ) Paul Biggar talk about why AOT might be better then JIT. His reasoning was that the suffer from bad startup times and php is a language where the comon uscase are scripts that only run a short time. Anyway the static compiler certantly wasn't a bad way to get some speed fast. Getting some type in there is probebly the best thing you can do :) Where can I get some more information about tracelets. I have never seen litrature about it. Did you guys invent that yourselfs? I have been thinking about something simular. If you have a language that is dynamic but is suited for static compiling (dylan for example). On could write a compiler that does all kinds of optimization and then spits out a bytecode that is suited for the JIT. Then at runtime you let the JIT do the rest. Im not sure if this is such a good idea because the static compiler would take away some opportunities for the JIT to do an even better job. Thoughts anybody? Thats the problem I always have. For every language I think about how good it would work with pypy. Someb

Tech talk related to PhD thesis on ahead-of-time PHP compiler

[link] - "Design and implementation of an ahead-of-time compiler for PHP" is the PhD thesis in question. A google tech talk related to this work is on youtube [this video] You can find multiple other papers on google scholar where Paul was an author all related to programming languages, compilers etc.
