What’s up with HandlerSocket?

I’ve presented at two different venues about HandlerSocket recently and the number one question that always arises is: Why hasn’t HandlerSocket become more popular than it is? Considering how fast and awesome HandlerSocket is, it’s not seeing as rapid adoption as some might expect. I theorize that there are five reasons for this:

FlashCache: more benchmarks

Previously I covered simple case with FlashCache, when data fits into cache partitions, now I am trying to test when data is bigger than cache. But before test setup let me address some concern (which I also had). Intel X25-M has a write cache which is not battery backuped, so there is suspect you may […]

Lighttpd as reverse proxy

We often recommend to set lighttpd in front of apache to handle http requests (more about http://www.mysqlperformanceblog.com/2006/05/21/speedup-your-lamp-stack-with-lighttpd/ ) , redirect dynamic requests to apache and handle static files by itself.
