Premature Optimization Mistakes
Ilia Alshanetsky (Oct 20, 2009)
Talk at ZendCon 2009 (English - US)
One of the thing that many people want to have is fast code as it allows handling of more data/clients with less resources, saving money and improving your overall efficiencies. However, premature optimization can often result in broken code, enormous amount of wasted time and missed deadlines. This talk will not only explain the common errors, but also offer easy performance solutions.

I'm not sure Ilia ever stops talking in his presentations. Not that it matters, his presentation was full of useful concepts, gotchas and best practices. Very informative, to the point that before I left the presentation, I had already deployed APC on one of my more popular site's server.

This should have been a keynote

I agree with "ANONYMOUS", this should have been a keynote. Ilia definitely earned several fans.

Undoubtedly Ilia was one of the best speakers. Most of his sessions were technical and that's what I expected at a World PHP Conference.
Questions:
1) output_buffering = On is that helpful really?
2) SQL Caching? Is it like dumping daily data into a table to generate reports easily instead of querying summaries from various tables?

The "output_buffering" buffering setting is helpful (especially when set a high value) when you are sending fair quantity of large PHP generated pages to the user.
"SQL Caching" could mean many different things, such as sql de-normalization for reporting purposes, etc... However what I was referring to was storage of SQL results in memory via memcache or apc, so that database does not need to be queried every single time.
