#1: PHP 64-bit binaries?

Posted on 2011-10-15 18:42:12 by Ivan Cenov

Hello,

I am searching for PHP binaries for Windows 64-bit.
It seems that such binaries are not supported officially at http://php.net.
There is some old unofficial binaries in the net.
Why there are no official support for Windows 64 bit?

http://www.anindya.com/ is the current up to date source and links to a small
library of 64 bit extensions ... as well as providing matching Apache 64 bit.

The 64 bit builds are not currently considered fully stable, but personally I've
not had any problems with them so far this year. They do need a lot of work to
clear a tranche of warnings in the 64bit compile logs.

From everything that I've heard, there is not much benefit to a x64
binary for PHP.

IIS can run in 32 bit mode...not sure about Apache, but you probably
already know that....

Running all 64bit including the database, I'm seeing a reasonable performance
improvement over a pure 32 bit set-up on the same AMD 64bit hardware using 64bit
vista order of 10 to 15% faster. It was also worth pointing out that the same
hardware runs a good 50% faster again on a 64bit Linux OS. I think this shows
that the OS is the problem rather than the 64bit software, but the Linux OS does
seem to use the multiple cores more efficiently. I've not tested both with a 64
bit version of Windows7, the full 64bit setup installed and ran, so I've not
bothered swapping to all 32bit.

yeah, running the database servers on 64bit is a must, mostly because of th=
e
memory limitations of the 32bit and the native 64bit int also has a
performance improvement for databases.
but we are talking about php here, not database servers, so that's not
really a valid point here.

would be curious that what would be the performance differences if
everything else would be the same, so only comparing 32bit php to 64bit php=
..
AFAIR 64bit php is a little bit slower.

PHP is slower in 64bit than in 32bit modes. Databases (be oracle,
mysql or other) are another stories and many of them are faster.
However one does not have to run php in 64bit mode to talk to database
servers running in 64bit mode.

That being said, the main issues are not only for php but many
libraries used by php. They did not support windows 64bit very well
and they have not been tested enough to be ran on production servers
safely (by all means).

xml files that were more than 3 gigabytes in size? Lets assume that this was
the only way to get this data, and this script was putting the data in a
database. I would not be able to do that operation in 32 bit php because the
entire xml file could not be loaded into memory.

The above example is more feasible then many would think (sometimes you have
no control over the format of the data you get). There are also other cases
where the memory address limitations of a 32 bit process could come into
play.

Well, right. The only advantage is the largest maximal available
memory. But I'd to say that if one is processing GB of XML data using
DOM, then he should seriously consider xmlreader and xmlwriter. They
are stream based parser and used a constant relatively low memory foot
print.

For the wincache example given above, if an app needs more than a
couple of GB for its user cache, solution like memcache should
seriously be considered. Opcode cache will certainly reach this value
in most cases :)

Hi!

I was also thinking about x64 php.
Guys, you said that 64 bit PHP is slightly slower than 32 bit, but there
might be areas where x64 will be faster. Let's imagine site basing on
image or video processing. That kind of site could take advantage of x64.

Lester gave us a link to unofficial x64 PHP, so compilation is possible.
Maybe it is a time to start publishing x64 alpha versions of PHP,
collect bugs information and so on.

Tomasz

I would not suggest to use php to process videos but to spawn the
processing to 3rd party servers using better tools.

As for images, for web images, x64 provides little gains except for
very few cases.

Not until libs have better support. We did that in the past and users
automatically used them instead of using the stable x86 builds. It
caused more work for no gain as we do not have the resources now to
fix all libs.

However, that does not mean we are not working on that but it is not
in the 5.4 roadmap.

I think that perhaps the thing that is different in all my testing is that
eaccelerator is enabled. That is compiled 64bit as are all the other additional
libraries I use, such as imagemagick and the firebird client. I need to produce
a set of publishable performance figures on the machine that I've been testing
on, but that would take some time as I am more than happy with the current all
64bit setup. Testing each bit as 32bit or 64bit would take some work, but I will
endeavour just to switch the php section ... if I can get 32bit versions of all
the libraries currently being used with it.

Mixing 32bit and 64bit just seems totally wrong to me ... and I am not seeing
any unexplainable problems with my current setup, which has been running since I
first posted the 64bit links without even having to reboot windows. Something I
still have to do on customer sites with the 32bit setups :(

did you checked your "Program Files (x86)" directory lately?
for windows it is common that there are apps without 64bit versions. :(

There is nothing wrong here but a totally normal configuration.

If one takes care of performances, the database server(s) are separate
servers anyway. And they are totally unrelated to the clients
connecting to them.

I see literally dozen. Many libraries do even claim no support for
win64 as it is totally untested and could suffer from many unknown
issues (including security ones). We have discussed that in the past
already and I would really appreciate that you stop to say that there
is no issue as it is totally misleading.

If these machines had to run anything other than the Apache/PHP/Firebird stack
that might be relevant, but my hands are tied by the customer to provide a
Windows based server rather than the preferred Linux setup. Most other things
are simply removed since they are not required, just leaving only the code
required to run the stack.

Yes Pierre - on the larger systems we run multiple machines, but on sites that
only require a single computer, a single clean stack is also nice, with
everything in the one base directory and without the agro of deciding if this is
a 32bit or 64bit program. Everything running on the Linux boxes is 64 bit, and
everything is built from the same code base, so I will continue to use a single
64bit stack ... and when problems arise then I will deal with them, but nothing
is giving me a problem currently ...

We are not talking about a linux stack here. And a server, even on the
same machine, has nothing to do with the clients connecting to it, as
explained earlier already.

? I'm running the full stack on windows as 64 bit code and seeing a performance
improvement over the 32bit version. Stripping parts out of the 64 bit stack and
just running them 32bit may be worth the effort, but *I* am happy that my own
PHP section running 64bit libraries for graphics and eaccelerator is running
faster than switching just that section to 32 bit. There way well be room for
improvement, but having to sort out which programs can be 64bit and which 32bit
is just messy. Apache running 64 bit IS faster so using a 32 bit version once
one switches to VC9 builds, so maintaining everything 64bit VC9 just seems
sensible. Exactly the same as it is on Linux anyway.

we are talking about your whole stack, as you didn't ran benchmarks using
32bit php vs 64bit php.

yeah, using 32bit php should gain you a little bit performance gain, and
more stable and supported build.

how do you know that it is running faster? did you benchmarked it against
the 32bit version? I thought that you didn't.

yeah, life is a bitch.

are you sure?
I didn't really see any benchmarks supporting that fact, let alone for
windows, which is usually less of an interest for the apache httpd
developers.

yeah, if you are using php as an apache module, but if you use for example
fastcgi, you can run 32bit php with 64bit apache or vice versa.

Quoting your last mail:

" Everything running on the Linux boxes is 64 bit, and everything is
built from the same code base, so I will continue=A0to use a single
64bit stack ..". So let stop this confusing discussion, points have
been made, we have ran extensive tests with all possible apps and
backends, PHP is actually slower and not stable enough and in some
extend less safe when built as 64bit. And I refer only to PHP and its
libraires here, not external tools like databases.

I haven't rolled back just part ... in fact I have yet to find 32 bit builds of
some of the extensions I use, but see last note ...

I've not rolled back to 32bit with 5.3.8 ... the base benchmark was back at
5.3.5 time frame, although I'm not seeing any difference between 5.3.7 and 5.3.8
on 64bit speed wise.

> Apache running 64 bit IS faster
> are you sure?
Fairly ... but I've just wiped the 32bit vista machine and that will have a
clean 64bit W7 next so I've got another chance to get the figures.

Anindya builds both x86 and x64 versions of Apache with VC9 since there are no
official builds of Apache we can use with PHP anyway, so complaining that I'm
not using an official PHP is a little academic anyway :) I'll run in just the
Apache first and play with that - but my benchmarks are on PHP :(

I only ever use php5apache2_2.dll in Apache ...

"so I will continue to use a single 64bit stack .. " on Windows since my
starting point is the 64 bit build of Apache using php5apache2_2.dll built from
the same code base as the 64 bit Linux stack ...
Since there are no 'official' VC9 builds of Apache we are starting from an
unofficial base anyway.

It would be useful to know where you are seeing stability issues since I have
yet to find any and have a number of fairly busy sites running on it. These are
all intranet, so have had quite a hammering from the IT departments security
wise without any failures, but are not accessible outside the network.
