So, by "9.10 slow" you mean the web browser you use is slow to load web
pages?

Which web browser?

FF has some known issues on recent versions of linux due to performance
problems with sqlite - beta versions of FF are said to be faster, but
google chrome leaves them all in the dust in my experience. I've
switched to google chrome as my default browser and for e.g. facebook
apps which are flash and javascript intensive, it's quite a bit faster
than FF.

I also prefer the behavior of chrome over firefox when there are
multiple tabs open and one of the tabs is waiting for a response from a
remote site. In this scenario, the whole FF is completely unresponsive
while waiting, but in chrome, all the other open tabs continue to
respond normally while the one tab is waiting on the remote server.

Once I got used to chrome, FF has seemed slow, sluggish and clunky.

Just my .02
