New SNS services are springing up everywhere and it seems that design decisions for these services early on is particularly important. If you can provide some design insights into this, many (including myself) would be very grateful.

Also, many people are now interested in new storage engines. However, informations on these new storage engines are rather sparse. It would be great if you can shed more lights on these topics.

By the way, thanks a lot for sharing valuable knowledge!

Sure. We publish all talks online http://www.mysqlperformanceblog.com/mysql-performance-presentations/

Thanks for feedback.

I think I tried to submit general performance tuning methodology session couple of times but it was not accepted. Though may be it is worth to try again this year. Indeed too many people do not approach finding bottlenecks systematic enough.

I did couple of presentations on benchmarking methodologies in the past and I think these are interest to relatively few people.

Also, how about a presentation on the methodology of performance troubleshooting or benchmarking. Many of your presentation focus on the testing of particular features, and what the numbers are, but this gets repetitive, even if they are kept current.

In general, I think there is too much focus on what the numbers are: “this is fater than that” ,etc. but not enough discussion about how to do a good benchmark properly, common issues to avoid, etc.

Also, one that focus on performance and profiling tools and methodologies for solving common problems in MySQL applications would be welcome. The important things is not what number to set this tuning variable at (though some people only care about that), but WHY particular values are better than others. how does it affect the behaviours.

You might have done something like this in the past, but I may have not seen it.
