I know that Symfony2 has been released, but is it production ready, or are they still finding and fixing so many bugs as to make it impractical?
How is performance in a production environment? Are there current benchmarks anywhere?
I’m looking to build an n-tier web site and am deciding on whether learning sf2 will be time well spent compared to just sticking with sf1.4.
What gaps are there in symfony2 – from what it seems there’s no official admin generator. Is anything else missing?
I have released a Symfony 2 based project that was featured in a major newspaper and did well. I’d deem it as production ready. I also did some load tests with jMeter and the man from the hosting company was impressed by the performance.
The only thing lacking IMO is the amount of tutorial and special articles that you have for Symfony 1. Nevertheless, I’ll use Symfony 2 for all my future projects.
One slight problem at the moment could be the hosting companies: You absolutely need PHP 5.3 (most companies still offer 5.2 only) and a caching mechanism (APC or memcached) for maximum Doctrine 2 performance.
