Might like to check out this FAQ

Possibly via WGET, or even the PHP cli.

Also, have a look at this FAQ;

How do I show page load time and DB queries?

SO you are being logged out when browsing around your site? Are you using an XOOPS custom setting (set in your XOOPS preferences)? Have you tried clearing your cookies?

If your site traffic is heavily centered around forum posts, then I would actually think twice about MySQL caching. On a site that is heavy on the database writes (such as a forum) it can actually slow things down even further. Using an Opcode accelerator (eAccerator/APC), HTTP compression, loading PHP as a module and optimising your XOOPS caching are all very well worth it though. There are many many threads on performance in these forums, you should be able to find plenty there.

Probably an autoincrement issue with a MySQL field. Will need full details of the duplicate key error...

Hi Javier,

You have a VPS, so you have the advantage of being able to tweak your server as much a you want to get the best performance. I suggest you look into the following;

Theme - Use CSS for positioning and reduce/consolidate images to reduce page weight and HTTP requests require to load the page.

Xoops Caching - In particular make sure your Xoop blocks are set to use caching as they are usually very expensive in terms of MySQL queries. Also look at module level caching as well.

PHP opcode cache - If your using PHP 4.x, then I suggest you have a look at eAccelerator to dramatically increase your PHP performance. If you are using PHP 5.x I would suggest using APC as I've read eAccelerator has a few issues with this branch.

Webserver - If your using IIS then you should configure your PHP application mapping to use FastCGI or ISAPI (FastCGI is better under heavy load). Looks like your running Apache so look at loading PHP into Apache as a module rather than CGI.

MySQL Query Caching & Buffer sizes - I see you have MySQL query caching already enabled, but be sure you've done your homework there. Due to the way query caching works it can actually really hurt performance if your site has a very heavy write load (such as forums, comments sections). Also look at tuning your buffers, for instance your key_buffer is set to 256MB which is 100% of your garanteed RAM.

Generally in a VPS you REALLY need to put the squeeze on the use of memory bound buffers and caches as it is usually a VERY limited resource. Once you have it tuned though your server should be able to handle just about anything. Have a read of the article I wrote about performance tuning XOOPS on IIS where I was able to gain around 1000% perofmance increase in some areas over the default install. It is about Windows/IIS, but very similar principals will apply to Linux/Apache. I also found a brilliant slideshow overview on php.net a while back explaining how to configure PHP with Apache to get maximum performance. Would be whell worth your while hunting that down too.

Hi All,

Helping a guy out with an his XOOPS 2.0.13.2 site at the moment and have install CBB 1.16a for him. Have an issue where the URL specified in mainfile.php is actually different to that which is shown in the address bar when viewing the forums. In mainfile.php he has got www.domain.com but when viewing the forums that domain changes to domain.com .

Only thing I could see that could cause it was the server_name PHP variable which was also set to domain.com instead of www.domain.com. To test the theory I had the system admin change the PHP server_name variable to another domain that this guy owns, and sure enough the domain shown when view CBB also changed.

I will probably just get the sys admin to change the server_name PHP variable to match that of the XOOPS_URL value in mainfile.php, but I was just wondering if anyone had any ideas as to why CBB doesn't use XOOPS_URL like other modules do?

Yep, this is one feature I'm looking forward to very much. Just hope that the XOOPS implementation of this is not too Apache mod_rewrite orrientated. I can be a right pain in the bum to get these clean url's working properly on Webservers other than Apache. Drupal and Wordpress come to mind...

Have you tried setting the "Article Display Layout" in AMS preferences to "By Topic". If you want seperate spotlight blocks for each topic using the AMS Spotlight feature, then all you have to do is create a spotlight mini block for each of your topics. Once that is done configure each mini block to "Latest in Topic" and then set the appropriate topic that should be used for that block.

Alternatively to that, have you checked out phppp's articles module? I really think it is one of the most promising for article management with Xoops.
