Great!

How you built Pharo image for Spur?
I read from Eliot mails that for Squeak he has something like 'Sput bootstrap: 'some.image'.
Do you implement something similar? If yes then why converting Pharo3 images will not work?

we adapted same bootstrap

it will not work for pharo3 because we need to add some classes, modify some others and reload the old class builder to bootstrap (and the new class builder needs to be fundamentally modified).

so is a lot of work, and does not corresponds to a stable version.

also, Spur will be stable some months from now� so it has sense to make it for pharo4 and not for older versions.

Hi,

I�ve been working on prepare Pharo to run with the new Spur VM� and finally this week Guille and I sit together and make a huge advance :)

here a screenshot of pharo 4 running with spur:
<Screen Shot 2014-07-02 at 15.58.17.png>
for more information, same image before migration, with a regular cogvm gives this numbers: '1297023432 bytecodes/sec; 161029354 sends/sec�, so that means that the tiny benchmarks run at 166% the speed of the old vm�

Of course this is just one benchmark, but I�m very impressed :)

Now, it is still not usable but I�m confident I can put a jenkins job to work very soon :)

Esteban

ps: before you start asking: Spur WILL NOT be available for Pharo3, it will be part of Pharo4.
