Strange, how often do you open/close your browser?
Whenever Firefox memory use has ballooned to over 1GB.
Which is pretty much daily.

For me it's UI responsiveness - seems I must be one of few people in the world that care about it since I've never seen any article or benchmark on that (there was a couple about startup times), so I'm not even sure if it isn't only a matter of perception, but for me the problem with Firefox is that the UI feels slow, like there is a lag between clicking on an element and an action being taken by the program. Safari…
UI responsiveness never seems to get the love it deserves. That I can count the time taken to respond to right-clicking a project in Eclipse on every machine and OS I have available is shocking. How can people use this software?
Are you doing Android development? If so, Eclipse 3.6 isn't compatible with the ADT plugin. I had the same slow downs, but moved back to 3.5, and it works fine now.

#83Browsers keep improving JS speed, but is there an upper limit to how fast it can be? How far off is it from something like C ?
There might be an upper limit on the speed of the language itself, but what has a lot more room for improvement is speed of DOM operations and DOM rendering. Since you could involve all kinds of fancy graphics hardware acceleration in that, as IE9 is purported to do, there's a lot more to be done there.
Most JS developers agree now that the slowest operations are DOM operations so they are avoided as much as possible.

#84Can anyone elaborate on the XPCOM improvements? I thought the plan was to get rid of XPCOM all together in firefox 4. Very nice set of improvements though. Not sure about firefox 4, but firefox 3 was a memory hog.
>... but firefox 3 was a memory hog. I really do not find Firefox 3 to be a memory hog at all. I find it to consume much less memory than Chrome running multiple tabs over a prolonged period of time. I have caught Chrome running way out of control with memory usage and nearly maxing out my page file. My usage generally has Firefox using between 300MB and 500MB or RAM depending on what I have open. The same usage on C…
I used to be a die-hard firefox user and I also used to write extensions for it for fun and professionally as well. I always say it's the only browser that I've read the source code for.(well, some of it at least)
The thing that bugged me with FF3 was that it never seemed to reclaim the memory that the tabs were using after being closed. I noticed that when you have say >20 tabs open. I often had to save my tabs and kill FF so that it doesn't bog down my system.
Now I'm using chrome which still is not perfect especially when you have say gmail and gmaps open and several other tabs. But killing the tabs does seem to make the app snappier again.

What platform do you run? I am on Linux x86_64 and Fx4b7 takes almost 10% of my RAM and ~20-30% CPU with two tabs open. With the same tabs open in Chromium, I get 2.7% RAM usage and 0-5% CPU usage. Maybe Fx has been really optimizing for Windows lately, but the performance on Linux x86_64 is not very satisfactory.
I am on OS X (10.6.5). I did not see FF4 CPU usage anything near what you are seeing. My CPU is ~2-3% with 6 tabs open (2 being Gmail). RAM usage is steady after a day of using the same browser process.

JS speed has improved so much recently due to optimisations like JIT (Just In Time compiling). There will be an upper limit eventually but we haven't hit it yet. It's damn fast but still a high-level interpreted language - time is taken for a program in the browser to compile it on the fly and run. It wont hit the speed of well written C code, but most things don't need that speed anyway.
I was browsing the language shootout the other day and came across the page for the regex test. I'm not sure how it's doing it or if something is wrong with the test but V8 is outperforming everything else, including C. That's the only test it leads though. Here are the results: http://shootout.alioth.debian.org/u32/performance.php?test=r... Also worth noting that TraceMonkey isn't too far behind. Does anyone know wh…

Look at the source code of the C program. It uses glib and the TCL libraries and it even includes locking for the multicore benchmark.
Look at the source code of the other C regex-dna programs which don't use glib or Tcl libraries.
