Can you explain what the -optimize > switch does? Well, it (normally) optimizes the code. It enables things like copy-propagation and dead-code elimination, which I assume are enabled by default in Gambit. I can't explain the slowdown.

I assume there isn't. The simple tests I did ran at about the same speed, but this may be different for your tests or continuation-intensive things. cheers, felix ___ Chicken-users mailing list Chicken-users@nongnu.org https://lists.nongnu.org/mailman/listinfo/chicken-users

BTW, did you use the "-optimize" switch? I did not use the "-optimize" switch for the experiments reported previously. The reasons are explained in the Scheme workshop paper (which by the way is now available here: http://users-cs.au.dk/danvy/sfp12/programme-sfp12.html). I just ran the experiment on V8 with Spock, this time using the "-optimize" switch. The results are: Execution times using V8 (Chrome 21.0.1180.89): Gambit-JSScheme2JS Spock fib35 .801.541.9x2.40 3.0x nqueens12 .72 .761.1x2.34 3.3x oddeven .831.922.3x5.62 6.8x ctak.18 17.64 95.9x .66 3.6x contfib30 1.17 106.01 90.9x3.60 3.1x btsearch2000 1.35 25.40 18.8x9.28 6.9x threads10 1.34 24.68 18.5x4.71 3.5x So the -optimize switch has actually slowed down the execution on the last 4 programs (those which use call/cc). Can you explain what the -optimize switch does? Note that these experiments were done with a previous release of Spock (the one that was current on July 6... I don't know how to get the Spock version number from chicken-spock). I know that you have released Spock 0.9 but I had problems installing the new version on my OS X 10.8.1 computer so I can't say if there is an improvement in the latest version.

[Chicken-users] Chicken UK 2012 is this month :-D
Hello Chickens! September, once seemingly so distant, is now upon us, which means that Chicken UK 2012 is starting to come together. I've assembled a draft programme: https://wiki.call-cc.org/event/chicken-uk-2012 However, I'm really just writing it so we have some ideas for something to do each day; in practice, I plan to be flexible and consider the weather and what moods we're all in each morning and go from there ;-) There's several slots free for talks, if anyone would like to tell us about anything they've been up to. If everyone's too shy, I will do some more myself. You have been warned... If anybody doesn't know where to come to, email me offlist and I'll give you the URL of our "how to get here page" - I just don't want it getting into search indexes!
