-A sript called phpsdk-local.bat has to be put into the PHP SDK root. If present, it will be automatically picked up by the starter script. A template for such a script is included with the PHP SDK. This allows to automatically meet any required preparations, that are not foreseen by the standard PHP SDK startup. Be careful while creating your own phpsdk-local. It's your responsibility to ensure the regular PHP SDK startup isn't broken after phpsdk-local.bat was injected into the startup sequence.

 The SDK tools are based on the KISS principle and should be kept so. Basic tools are implemented as simple batch script. The minimalistic `PHP` is available for internal SDK purposes. It can be used, if more complexity is required. A suitable PHP binary is bound with the PHP SDK. If you have an idea for some useful tool or workflow, please open a ticket or PR, so it can be discussed, implemented and added to the SDK. By contributing an implementation, you should also accept the SDK license.
 
+# PGO
+
+As of the version 2.1.0, the SDK includes a tool for the [PGO](https://docs.microsoft.com/en-us/cpp/build/reference/profile-guided-optimizations) optimization. Several training cases are included by default, which are based on the real life opensource applications. The PGO optimization can give an overall speedup up to 30%. The work on adding more training scenarios for the widely used opensource apps is ongoing. If you have a training scenario to share, please create a PR to this repo. Any new training cases are thoroughly validated through the extensive performance tests.
+
+## Preparing PGO training environment
+- the pgo folder in the SDK root dir contains templates and scenarios for PGO training
+- adjust and execute [doc/phpsdk_pgo_prep_elevated.bat.example](doc/phpsdk_pgo_prep_elevated.bat.example) to open ports required for PHP SDK training servers
+- run `phpsdk_pgo --init`
+
+## Creating PGO build
+- compile PHP configured using `--enable-pgi`
+- run `phpsdk_pgo --train`
+- run `nmake clean-pgo`
+- rebuild PHP `--with-pgo`
+
+## Adding custom PGO training scenario
+
+A custom scenario can be used to produce a custom PHP binary dedicated to an arbitrary application. 
+
+The existing training cases can be found in [pgo/cases](pgo/cases). Assumed the case would be named `myapp`, the general steps to setup were
+
+- create the case directory under `pgo/cases/myapp`
+- create `pgo/cases/myapp/phpsdk_pgo.json` with the necessary definitions 
+- create `pgo/cases/myapp/nginx.partial.conf` with a partial NGINX template
+- create `pgo/cases/myapp/TrainingCaseHandler.php` with a class as defined in the [interface](lib/php/libsdk/SDK/Build/PGO/Interfaces/TrainingCase.php)
+
+After a training case is implemented and put under `pgo/cases`, the work environment needs to be reinitialized. The tool puts all the training data and necessary applications under `pgo/work`. Rename or remove that directory and rerun `phpsdk_pgo --init`.
+
+To skip a training case, add a file named `inactive` into the case folder.

-This directory contains data needed by Bison.
-
-* Skeletons
-Bison skeletons: the general shapes of the different parser kinds,
-that are specialized for specific grammars by the bison program.
-
-Currently, the supported skeletons are:
-
-- yacc.c
-  It used to be named bison.simple: it corresponds to C Yacc
-  compatible LALR(1) parsers.
-
-- lalr1.cc
-  Produces a C++ parser class.
-
-- lalr1.java
-  Produces a Java parser class.
-
-- glr.c
-  A Generalized LR C parser based on Bison's LALR(1) tables.
-
-- glr.cc
-  A Generalized LR C++ parser.  Actually a C++ wrapper around glr.c.
-
-These skeletons are the only ones supported by the Bison team.
-Because the interface between skeletons and the bison program is not
-finished, *we are not bound to it*.  In particular, Bison is not
-mature enough for us to consider that ``foreign skeletons'' are
-supported.
-
-* m4sugar
-This directory contains M4sugar, sort of an extended library for M4,
-which is used by Bison to instantiate the skeletons.
-
-* xslt
-This directory contains XSLT programs that transform Bison's XML output
-into various formats.
-
-- bison.xsl
-  A library of routines used by the other XSLT programs.
-
-- xml2dot.xsl
-  Conversion into GraphViz's dot format.
-
-- xml2text.xsl
-  Conversion into text.
-
-- xml2xhtml.xsl
-  Conversion into XHTML.

-
-# This skeleton produces a C++ class that encapsulates a C glr parser.
-# This is in order to reduce the maintenance burden.  The glr.c
-# skeleton is clean and pure enough so that there are no real
-# problems.  The C++ interface is the same as that of lalr1.cc.  In
-# fact, glr.c can replace yacc.c without the user noticing any
-# difference, and similarly for glr.cc replacing lalr1.cc.
-#
-# The passing of parse-params
-#
-#   The additional arguments are stored as members of the parser
-#   object, yyparser.  The C routines need to carry yyparser
-#   throughout the C parser; that easy: just let yyparser become an
-#   additional parse-param.  But because the C++ skeleton needs to
-#   know the "real" original parse-param, we save them
-#   (b4_parse_param_orig).  Note that b4_parse_param is overquoted
-#   (and c.m4 strips one level of quotes).  This is a PITA, and
-#   explains why there are so many levels of quotes.
-#
-# The locations
-#
-#   We use location.cc just like lalr1.cc, but because glr.c stores
-#   the locations in a (C++) union, the position and location classes
-#   must not have a constructor.  Therefore, contrary to lalr1.cc, we
-#   must not define "b4_location_constructors".  As a consequence the
-#   user must initialize the first positions (in particular the
-#   filename member).
-
-# We require a pure interface using locations.

-# In M4 1.4.x, every byte of $@ is rescanned.  This means that an
-# algorithm on n arguments that recurses with one less argument each
-# iteration will scan n * (n + 1) / 2 arguments, for O(n^2) time.  In
-# M4 1.6, this was fixed so that $@ is only scanned once, then
-# back-references are made to information stored about the scan.
-# Thus, n iterations need only scan n arguments, for O(n) time.
-# Additionally, in M4 1.4.x, recursive algorithms did not clean up
-# memory very well, requiring O(n^2) memory rather than O(n) for n
-# iterations.
-#
-# This file is designed to overcome the quadratic nature of $@
-# recursion by writing a variant of m4_foreach that uses m4_for rather
-# than $@ recursion to operate on the list.  This involves more macro
-# expansions, but avoids the need to rescan a quadratic number of
-# arguments, making these replacements very attractive for M4 1.4.x.
-# On the other hand, in any version of M4, expanding additional macros
-# costs additional time; therefore, in M4 1.6, where $@ recursion uses
-# fewer macros, these replacements actually pessimize performance.
-# Additionally, the use of $10 to mean the tenth argument violates
-# POSIX; although all versions of m4 1.4.x support this meaning, a
-# future m4 version may switch to take it as the first argument
-# concatenated with a literal 0, so the implementations in this file
-# are not future-proof.  Thus, this file is conditionally included as
-# part of m4_init(), only when it is detected that M4 probably has
-# quadratic behavior (ie. it lacks the macro __m4_version__).
-#
-# Please keep this file in sync with m4sugar.m4.

-# m4_foreach(VARIABLE, LIST, EXPRESSION)

-# whole list must *quoted*.  Quote members too if you don't want them
-# to be expanded.
-#
-# This version minimizes the number of times that $@ is evaluated by
-# using m4_for to generate a boilerplate into VARIABLE then passing $@
-# to that temporary macro.  Thus, the recursion is done in m4_for
-# without reparsing any user input, and is not quadratic.  For an idea
-# of how this works, note that m4_foreach(i,[1,2],[i]) defines i to be
-#   m4_define([$1],[$3])$2[]m4_define([$1],[$4])$2[]m4_popdef([i])
