-The http protocol also works, path is the same.
+If you are inside a corporate firewall, git:// may not always work for
+you. In that case you can use the http protocol, path is the same:

Snapshots are frequently generated and they include the git meta data as
well. You can download them here:
Building
--------
-Just type 'make' and 'make install'. If on BSD, for now you have to
-specify the BSD Makefile with -f and use gmake (not make), eg:
-
-$ gmake -f Makefile.FreeBSD && gmake -f Makefile.FreeBSD install
-
-Same goes for AIX:
+Just type 'make' and 'make install'.
-$ gmake -f Makefile.aix && gmake -f Makefile.aix install
-
-Likewise with OpenSolaris, use the Makefile.solaris to compile there.
-The OpenSolaris make should work fine. This might change in the
-future if I opt for an autoconf type setup.
+Note that GNU make is required. On BSD it's available from devel/gmake;
+on Solaris it's in the SUNWgmake package. On platforms where GNU make
+isn't the default, type 'gmake' instead of 'make'.
If your compile fails with an error like this:
based distros, it's typically called libaio-devel.
+Windows
+-------
+
+On Windows Cygwin (http://www.cygwin.com) is required with at least
+devel/gcc4 and devel/make installed in order to build fio, and
+admin/cygrunsrv to run it. You can also install devel/git to fetch/update
+the source files. To create an MSI installer package put a copy of Cygwin
+in os\windows\fio, install WiX 3.6 from http://wix.sourceforge.net/releases/
+and run dobuild.cmd from the os/windows directory.
+
+Before running fio you'll need to have a copy of cygserver running. Run
+"/usr/bin/cygserver-config" from an elevated Cygwin shell (i.e. launch the
+Cygwin shell under the Administrator account) to configure it. Once
+configured, run "net start cygserver" to start it, or type
+"/usr/sbin/cygserver &" in the Cygwin shell to start a local copy.
+
+If fio exits with the message "Bad system call" it normally means that
+Cygserver isn't running.

Any parameters following the options will be assumed to be job files,
process Dump info related to processes
file Dump info related to file actions

can be used to gauge hard drive speed over the entire
platter, without reading everything. Both x/y can
include k/m/g suffix.
- iolog=x Open and read io pattern from file 'x'. The file must
- contain one io action per line in the following format:
- rw, offset, length
- where with rw=0/1 for read/write, and the offset
- and length entries being in bytes.
+ read_iolog=x Open and read io pattern from file 'x'. The file format
+ is described in the HOWTO.
write_iolog=x Write an iolog to file 'x' in the same format as iolog.
The iolog options are exclusive, if both given the

+ read iolog will be performed. Specify a separate file
+ for each job, otherwise the iologs will be interspersed
+ and the file may be corrupt.
write_bw_log Write a bandwidth log.
write_lat_log Write a latency log.
lockmem=x Lock down x amount of memory on the machine, to
Platforms
---------
-Fio works on (at least) Linux, Solaris, AIX, OSX, NetBSD, Windows and FreeBSD.
-Some features and/or options may only be available on some of the platforms,
-typically because those features only apply to that platform (like the
-solarisaio engine, or the splice engine on Linux).

Some features are not available on FreeBSD/Solaris even if they could be
implemented, I'd be happy to take patches for that. An example of that is
