@F0l2saken: not trashing Joomla 1.5 - just pointing out some issues - for more information please look at www.joomlaperformance.com/

@THE_AI: Agree that the potential might be in Joomla 1.5 framework - but its really upto the developers to adapt and take advantage of it. Users, in the long run, just care about what is available and how well it works. The CB Team is not trashing/bashing Joomla 1.5 vs Joomla 1.0. I have just stated some not so obvious facts that very few users are aware of. It is there choice to make - as long as they have all the facts clear.

@both: As stated, just because CB 1.2 works on Joomla 1.5 without the legacy plugin does not mean that all the 3PD CB plugins are automatically native joomla 1.5 compatible.

Quick replies:

- avatar upload at registration isn't in 1.2, but the API will make a plugin easier.

- thanks for the feedback on the about screen, we will try to look into that.

- regarding Joomla's legacy plugin, I fully agree it's a good thing, and it doesn't influence performance for more than a few percent (on PHP 5.x), plus as most people don't understand it allows native+legacy so you get best of both worlds, so it's an AND and not an OR, as some think.

- regarding Joomla 1.5 performances, we didn't bash , and are really sorry if it has been taken like bashing, as it wasn't our intention at all . We can only agree that the 1.5 API is an evolution from the 1.0 API, and adds lots of abstraction layers and an improved MVC model. However, all of this nice features have a cost in performance that one has to be aware of, before migrating a busy Joomla 1.0 site. Some CB-powered sites have 5000+ users online simultaneously on a dedicated single server, and typically this is a scenario where i can't recommend jumping on joomla 1.5 for now.

I also had to single-step through Joomla 1.0 and 1.5 as well as Mambo many times during weeks to understand bugs, and workaround them, so I think by now i pretty much have a feeling on the current web-page executions, and can see that there is room for performance improvements in all systems, but particularly in Joomla 1.5, which is a good thing, because that means that it will most probably be improved in future versions.

Here the reference regarding the performance test results:
www.joomlaperformance.com/articles/benchmarks/benchmarking_joomla_1.5.1_40_15_5.html

Please don't misunderstand us again, we are not pointing our fingers anywhere, just think that it's to early to deploy Joomla 1.5 on an existing busy website with a limited-resources server, if you don't badly need the new API. This will certainly improve over time, and our advice will most probably change in the future.

If you have reasonable server resources, and reasonable traffic, you can certainly give it a try, but we were specifically raising a warning for upgrades of existing websites:

Also, people rushing to install or migrate existing Joomla 1.0.X websites to Jooma 1.5.1 should really do their homework first.

Sorry if that wasn't clear and got misinterpreted. Hope the above clarifies.
