Adrian, That's a pretty good summary of the details I listed. Perhaps more important, I am suggesting that we create benchmarks of a typical number of open browsers' response to normal use. We should probably also parameterize the theme in use and the options (Shout, free type, rounded corners, etc.) that are enabled, to allow us to compare the effects of the "luxury" items. Ideally, the benchmark would run all of the combinations and leave behind a text file identifying the also the contributor and their description of the machine, allowing us to see what clobers us on which OS+hardware. The category change I had in mind was of a class, in particular, suppose I have packages SpellingErrors-Stupid and SpellingErrors-ReelyStupid, and want to change the second one<g>; OB really ground to a crawl on things like that.

Hi Bill, David and Alex made couple of speed improvements in OmniBrowser during yesterday's sprint. I will let them detail on what they achieved so far. Summarizing your mail below, the following are the most important actions to optimize: - response to keyboard input - time delays selecting a new class or method - time required to recompile a class - changing the category (class or method?) Anybody interested to do benchmarks of these actions (e.g., comparing Pharo to Pharo-core)? Cheers, Adrian On Jul 4, 2009, at 21:08 , Schwab,Wilhelm K wrote:
Adrian,
I share Stef's enthusiasm for your suggested process. Thanks for taking my prods about speed in the constructive spirit in which they are intended.
One concern though: is the benchmark of opening and closing browsers able to give a realistic comparison of performance? Time to open a debugger is probably worth noting, but the things that concern me most with the browsers are poor response to keyboard input, time delays selecting a new class or method, and (most notably) time required to recompile a class; changing the category can take several seconds in my experience.
Re keyboard input, I suspect characters are being lost; in fairness, that is difficult to test, because it requires typing quickly and accurately. Still, Pharo strikes me as just not being able to keep up, and it's worse with the package browser. You are of course correct to keep free type and Shout on the list of suspects, though I must say that Shout has always struck me as eerily fast.
In short, I do not dispute that the difference is speed is small, especially for the open/close that is benchmarked. However, there is simply no "extra speed" to waste. Ideally, benchmarks should compare the different browsers with and without shout and free type, rounded corners, etc., and should separate selecting a new class and method.
Some of my trouble might stem from using Linux for much of my work. I cannot describe the extent of my frustration with Windows - I've had it and then some. I'll stop the rant there (yes, I could go on for a while yet<g>). However, I cannot in good conscience join the "Linux is faster than Windows" crowd, and I am willing to consider the possibility that the display handling in the linux vm (no accusations, just in the interest of intellectual honesty) might have room for improvement, and/or the design of X-windows might not help.

Hi Bill,
Performance is certainly important. Please don't stop bugging us to make progress at this front too ;)
What we should start with is to identify which features makes it slow.
I recently posted basic benchmarks [1], but we need to identify single features so that we know where to optimize or which features should better be disabled.
What would help is if you could tell us what exactly is slow (at the moment I'm mainly working in the core image without freetype fonts and speed feels ok on my MacBook Pro).
Cheers,
Adrian

Stef,
Understood, but since you appear to be leaving open things that I consider to be drastic (removing traits), it only seems reasonable to try the faster browser on some slower machines to see what impact it makes. It would not take too much prodding for me to be able to give some guidance along the lines of "not enough impact to be of help" or "well worth adopting." _Something_ is eating up a lot of clock cycles at present.

Is there a way to get the fast browser, or an image with it loaded?

Hi oscar
Ideally we would love to have a fast browser with package support: - dual browser - class extensions - traits - refactoring - icons
Now apparently OBEnhancements was a bit dirty and this is not clear what colin will integrate or not. Lukas has a OB version which is fast but it does not have - dual browser - class extensions - traits - icons So david and lukas should talk a bit more and we could get the best of the worlds. Saturday we should have a discussion. Having a fast but powerful browser is important and right now if the browser does not support trait then we should remove traits from the image. Similarly we cannot work well without class extension support and other package related functionality. Stef

Hi Folks,
I am trying to port Squeak by Example to Pharo by Example. I am a bit confused about what is suppose dto be the standard browser now. I thought it was the OB Package Browser, but Damien Cassou just gave me a new image where the browser is an OB System Browser (Categories, not packages). I cannot even see any more how to switch between the two.
Can someone enlighten me? (Then I can explain it in the book.)
