eZ publish performance

Friday 04 November 2005 7:19:10 am

Hi

Here's a few tips for your pagelayout:
- You can safely add the <i>ignore_content_expiry</i> to several of your cache-blocks.
- Looks like you might be able to use cache block with keys=(node_id, user_id) ( I'm not sure though, as I do not know exactly what is displayed there ).
- Try using <i>subbtree_expiry</i> where you can not use the <i>ignore_content_expiry</i> option.

Hi,

I wonder if this could give an insight into the problem. I notice that if I try to run:

[onewaggr@web3 php]$  ./bin/php/eztc.php -s 2gc_intra
-bash: ./bin/php/eztc.php: No such file or directory

or:

[onewaggr@web3 php]$  ./bin/php/eztc.php
-bash: ./bin/php/eztc.php: No such file or directory

It wont execute. If it won't execute via shell then perhaps its not doing so when executed via the admin panel?

What are you thoughts? Does this point to a ini misconfig somewhere?

Regards, Steve.

Steve, files under /bin/php/*.php are normal PHP scripts, so you should execute them via PHP CLI.

cd ezpublish_root
php runcronjobs.php

or

cd ezpublish_root
php bin/php/eztc.php -s siteaccess

Yes, this will work only when you will execute this script from EZPUBLISH_ROOT directory, like:

$ php bin/php/eztc.php -s intranet

not from EZPUBLISH_ROOT/bin/php

Hi Steve,

you didn't answer the question if you are running an php accelerator like eaccelerator.

If you don't know it, take a look at the system information within the admin siteaccess.

As already mentioned you need to install it to decrease your load times.

If you have already installed one, I would check the permissions to the directory where the cache files are stored.

Mit freundlichen Grüßen
Best regards

Steve, do you have any errors about wrong permissions. Look in to ezpublish log directory and check error.log.

Xavier,

Many thanks for the input - it has shaved some time off the loading (about .5 sec).

I'm really pleased to say we have it solved :) Got some tips from PaulF and have added additional lines to our sites.ini file. Before we had:

[TemplateSettings]
TemplateCache=enabled
TemplateCompile=enabled

now we have:

[ContentSettings]
ViewCaching=enabled

[TemplateSettings]
NodeTreeCaching=enabled
TemplateCache=enabled
TemplateCompile=enabled
TemplateOptimization=enabled

...and its loading really quick!

Thanks for the input on this.

Regards, Steve.

Hi Lukasz,

We have a much better system, but its still not as good as I'd like it. The server is:

OS Name	Microsoft(R) Windows(R) Server 2003, Standard Edition

Available Physical Memory	1.47 GB
Total Virtual Memory	3.85 GB
Available Virtual Memory	3.45 GB
Page File Space	2.00 GB
Page File	C:\pagefile.sys

As youcan see, its a beast! This site should be flying.

To get it to its current state (which is not too bad) we have:

- added the site.ini tweaks as per above (they weren't in siteacesss) - this gave the biggest boost by a long way

- changed the caches so we just have 2 big caches (both uri), one containing everything above maincontent, and one containing everything below. We'll have to break this up into a few more blocks as we have a bookmark function on the page as this cant be in the block.

- added eaccelerator, tho' so far we havent noticed much improvement

- we have php.ini at 28m memeory alloc (is there a benefit to increasing this further?)

Loading the homepage after its been loaded previously following as cache refresh we get:

AFAIK, we should be getting better results than this, tho' thanks god the system is now useable.

On another tip, I'm now scared of ever clearing the template cache - as soon as I do so the client has to deal with massive page load times when they view the page first time.

Is there no way of getting ez to re-generate all the pages via a script (PaulF was talking about wget to 'ping' all your site pages) - eztc.php gets some way there, but it doesnt get rid of these horrible initial load times...?

Any thoughts on this?

Regards, Steve.

Steve, which version of eZ publish do you use? This can be weird but ... have you tried with other version of eZ publish then your site uses?

Just test with plain installation of newest version.

Look also on:

You can also get better results with static cache. Check documentation and forum for more info.
