[symfony-users] Re: Performance optimization!HELP!!
Make sure you've read http://www.symfony-project.org/book/1_2/18-Performance - lots of good advice there. http://www.symfony-check.org/ is another useful site. In order of the biggest improvement for the least amount of effort, I'd say: 1. Install a PHP accelerator 2. Make sure your db tables are properly indexed 3. Minimise the number of queries with joins Anything after that starts to get increasingly more time consuming to implement for smaller and smaller gains. If you're using multiple web servers, look at using memcached for session storage and for the view cache. Do not be tempted to share via NFS as it will kill your performance.

That's always going to be the case if you are replacing joins with multiple queries that does the same thing. You're replacing in-memory and highly optimized database code with multiple trips over the wire (even localhost has a delay) plus query parsing plus result set parsing plus object hydration. Reducing joins only works in a handful of special cases like: 1) denormalize the data so you don't need to join to return the same result set, 2) if you can get the same result set by skipping a join, 3) you can eliminate some data from the result set to remove a join. -- Jacob Coby --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "symfony users" group.

I work on a site with huge traffic and memcache has been fantastic. -- --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "symfony users" group.
