+HippyVM - yet another attempt at PHP performance
+------------------------------------------------
+
+Who am I?
+---------
+
+* Maciej Fijalkowski
+
+* PyPy developer for about 8 years
+
+* main author of hippyvm
+
+* founder of baroquesoftware.com
+
+HippyVM
+-------
+
+* a PHP interpreter (essentially), runs php code
+
+|pause|
+
+* has a just in time compiler, which makes it fast
+
+|pause|
+
+* dual licensing, commercial and open source
+
+HippyVM status
+--------------
+
+* runs a lot of PHP test suite
+
+* misses a lot of builtin functions
+
+* can kind of "run" wordpress, mediawiki, getting there
+
+* cgi, fastcgi (not open source)
+
+* quick    XXX do you mean 'fast'?  but next slide already says 'fast'
+
+HippyVM status - short
+----------------------
+
+* fast, compliant
+
+* not quite ready
+
+Let's talk about performance
+----------------------------
+
+* "I want my website to run faster"
+
+* "I'm going to compare various languages, implementations"
+
+|pause|
+
+* "I'll use a recursive fibonacci function"
+
+Performance
+-----------
+
+* a very complex picture
+
+* bottlenecks depend on the use case
+
+* libraries, programmers, styles matter
+
+Performance - let's try science
+-------------------------------
+
+* get a set of programs (small, medium, large)
+
+* compare them
+
+* don't use a single number
+
+PHP performance
+---------------
+
+* number of requests per second
+
+* loading the code
+
+* accessing the DB
+
+* gluing it all together
+
+PHP performance landscape
+-------------------------
+
+* Zend PHP
+
+* HHVM
+
+* php-ng
+
+* HippyVM
+
+* other projects
+
+Current HippyVM performance
+---------------------------
+
+* we can't really compare large things (mediawiki ~on par)
+
+* small and medium between 2x faster - 2x slower than HHVM
+
+|pause|
+
+* very hand-wavy, but you really need to do it yourself
+
+|pause|
+
+* consider bottlenecks differ depending on implementation
+
+Performance - personal opinions
+-------------------------------
+
+* the language should be easy **for a programmer**
+
+* the language implementation can be complex
+
+* libraries, patterns and the ecosystem matter for anything non-trivial
+
+Performance - questions
+-----------------------
+
+* ?
+
+HippyVM history
+---------------
+
+* started as a facebook research project
+
+* got some funding to pursue as a commercial project
+
+* an offspin of PyPy technology
+
+PyPy
+----
+
+* a fast, compliant Python interpreter
+
+* 0.5%-1% of Python market share
+
+* a framework for building efficient interpreters
+
+* 10 years of research
+
+* fully Open Source, EU funded project
