Important CPU abuse from Php

G'day irradiate. I use Webcity. One of the best decision I ever made in my entire life! Rock-solid, beautiful service! Ridgey-didge.

Give me a telephone call and we'll discuss what's going on (contact me by PM).

The core joomla sef thingie doesn't have any problem irradiate

G'day, irradiate. Thanks for your phone call late yesterday arvo. I'm sorry we didn't get to the root cause of your problem but I've had a think overnight and I wonder whether these theories might help.

To summarise the situation, irradiate has a working website that is based on Joomla 1.0.x with Simple Machines Forum and a bridge. He's looking for forum component that seamlessly integrates with Joomla (like all of us) and has decided to use Kunena. He wants to convert his SMF data into Kunena (involving over 46,000 messages and 1,500 message categories) and transport the forum data and his users to a new J! 1.5 website. The old J! 1.0 website runs off-shore; he's established his new J! 1.5 site here in Australia. His Australian hosting company claims that, for a period of time, the use of his forum was placing excessive processing demand on the servers and have threatened to cut-off his access if he doesn't do something about it.

We don't know the extent of the hammering that's directly due to Kunena. What's quite inexplicable is that the new J! 1.5 site is not yet in production. This means that the only server activity has been due to a handful of users.

I wonder whether the hammering of the webhost's servers occurred during the conversion from SMF to Kunena? I wonder whether was phpMyAdmin was instrumental ... not Kunena itself?

irradiate doesn't use any SEO components (which might have some impact on the number of SQL queries). As Matias has stated, it's not necessarily the volume of SQL queries, it's the way Kunena's queries are constructed that could affect processing performance.

I'm therefore as perplexed as irradiate is as to what narked his webhosting company (the same service that I also use and have no problems with) when he makes use of his website. If he allows users to his site, will it cause an unacceptable demand on server processor availability? Or perhaps the reported surge only occurred during the SMF-Kunena transitional phase?

Does anyone possess SQL performance metric analysis tools that might assist irradiate to pinpoint the source of the problems?

Thanks

Ask the host to provide some documentation of this abuse. My advice would be to install and test locally and do the conversion. When done upload and install a Joomlapack archive of the completed conversion to the remote server.

Question. Why is this posted in the Kunena 1.0.6 – 1.0.9 and Fireboard forum?

G'day, GM. The topic was created in this category because, at the time, irradiate was using Kunena 1.0.9. He has only, in the last couple of days, upgraded to K 1.0.10 but not for reasons of performance. He is yet to make a couple of post-upgrade changes (such as fixing the broken K 1.0.10 search function, and others) listed in the "solutions and fixes" discussions.

You're quite right, too, GM - and irradiate and I agreed last night - that further empirical evidence (from the webhost) is needed. Fortunately, the webhosting company provides an excellent telephone support service.

Don't speak too soon about the support from webcity..... Its been pretty hopeless to say the least.

I finally got ssh access to have a look at the mysql slow queries log to find that they are empty! I contacted the host again and after waiting two days for a reply email (I also rang but they said the response had to be by email) and they explained that the logs are emptied by them and that they have another log that I can't have access to.

They have offered to have a look at the site for me and try to rectify the problem for a fee per hour.... and they don't know how long it will take and require payment up front :blink:

So, I'm now in the process of changing hosts and while doing it noticed the Joomla error log is pretty big. Had a look and I'm not too sure if anything is of use in it but here is the errors leading up to the point when they suspended me.

Again, I don't know what I am looking at, so I thought I would throw it up here incase it has any information.

All those error 2006s means there is a massive timeout on the server.

Yep... I would go either for an error on the server, or a bad installation... you sure kunena installed without problems?

I had LOTS of MySQL server dead errors in IXWebhosting (avoid it!) moved to sureservers, and all is fabulous, no error on about 3 months, and site is superfast!

Although this could be a problem with the hosting service, the best way to confirm if it's Kunena causing the problem would be to create a brand-new J! 1.5.10 website (if you're really adventurous and want "to boldly go where no-one has gone before" - well, not with success anyway - use J! 1.5.11) and nothing else but Kunena 1.0.10, import your data there and report if you're experiencing performance problems.

This could be Kunena, or the database, or the MySQL server ... or any one of the dozen additional Joomla extensions/templates that irradiate is using.
