I was testing 5.3 on my windows box. Surprisingly I noticed an way higher performance again as expected. I was expecting round about 20 to 30 % gain, but it turned out that I had gained round about 90% in performance.

As I said on windows. Is one free todo the same tests on a linux box just for fun? If so share the results.

Here are my results on WINDOWS VISTA / MYSQL / APACHE / FASTCGI + WEBIN.

One more with php53 and define ( 'EZP_INI_FILEMTIME_CHECK', false );

EZP_INI_FILEMTIME_CHECK gives 30 % on top

Björn,

that is good news. It is not unexpected. The problem on windows has been the file i/o. In PHP 5.3 the Microsoft team have totally rewritten this and they were arguing that we should see the same performance on Windows as on Linux with PHP 5.3. This seems to be the case (or close to), I have not yet benchmarked this myself though.

I can confirm this, tested this a while back with alpha builds.
So a big present for us Windows developers, and also makes it more feasible to run eZ Publish on Windows servers.

"and they were arguing that we should see the same performance on Windows as on Linux with PHP 5.3"

This is an overstatement, at least for eZ Publish. I have about the same numbers as Björn, and my Linux x64 distro on the same machine gives me close to 40 Requests per second with php 5.2. From what I understood from Derick, some of the difference also comes from the slower process creation speed on Windows and slow POSIX emulation layer, not sure if they have worked on those parts as well though.

But, using IIS fastcgi and x64 builds of PHP will probably get you close to a third of the performance you get on Linux, so a lot better then 1/10 in earlier versions:)

Hi all,

One of my client wants eZ 4.1.3 with php 5.3. I think we should wait to upgrade to php 5.3.
Are there known bugs ?
What is the official answer of eZ Systems on that point ?

André R.

There is no official response yet as we haven't been able to test it properly yet (something QA will do as part of the 4.2 release cycle sometime in august).

A quick look in the php issue tracker might suggest that you should wait for 5.3.1, as there are a couple of reports that seem to affect eZ Publish badly if they are true. (parent::func() and misc file system stuff on Windows).

@nicolas you should also keep an eye on this issue in the eZ gtracker: http://issues.ez.no/IssueView.php?Id=13825

and of course wait for a stable release of eaccelerator/xcache/apc...

Hello,

we are running ez Publish 4.0.0 within a XAMPP 1.6.3a environment (with PHP 5.2.3).

I'd like to test the performance of ez Publish 4.0.0 with PHP 5.3 because we have some performance problems.

Does anyone know if there are any side-effects switching to PHP 5.3 and XAMPP 1.7.2?

Regards,
Mark

André R.

Side effects: plenty, especially since 4.0 does not support PHP 5.3. But it's mostly warnings <del>and errors</del> though, so feel free to try.

I think Andre meant "mostly warnings and not errors"...
