Are there any efforts being made in this direction to diagnose how a page's performance can be increased?

As far as I know,

opera:config#Always Check Redirect
opera:config#Always Check Redirect Images

became unchecked by default from Opera 10.

Opera now passes "Cache Resource Redir" test of Steve Souders' UA profiler <http://stevesouders.com/ua/>. (The table in the page is wrong)

If you turn off

opera:config#Always Check Never-Expiring GET queries

then Opera 10 passes "Cache Redir" test as well. "Always Check Never-Expiring GET queries" means to cache a request which has "?" in the URL and returns no explicit expiry date-time.

You're on the wrong side of the problem. I'm asking if any similar tools are being worked on for inclusion into dragonfly.

Oh I see. I guess there is not enough motivation to make the equivalent for Dragonfly since the information you get in the end is more or less the same as what you get out of YSlow and Page Speed.

But that's only my opinion.

I don't see your point here. Can't you get more or less the equivalent of Dragonfly in Firebug? Is that a reason for Opera stop working on it?

I mean many of the criteria like Minimizing round-trip times, Minimizing request size, Minimizing payload size (according to here <http://code.google.com/speed/page-speed/docs/rules_intro.html>) and Minimize HTTP Requests, Add an Expires or a Cache-Control Header, Put Scripts at the Bottom, Configure ETags, Reduce the Number of DOM Elements, and Do Not Scale Images in HTML (taken from here <http://developer.yahoo.com/yslow/help/index.html#guidelines>) are the same for Firefox and Opera.

Agreed. So your solution is to tell them to open firefox to find out why it's slow?

EDIT: IE has a tool as well now.

I'm not saying it's completely useless. But I would like Dragonfly dev team to develop something much more useful and no other competitors have done before.

Since site speed tool is more or less reinventing the wheel, Dragonfly team can make a public repository for it and leave it mostly to the community. I'd be happy to contribute.

Webkit (chrome and safari) has a similar tool in the works now. That just leaves Opera without. Is this being worked on/looked at?
