etoys very slow (12.04 LTS) on notebook

[Josep Pujadas-Jubany]

etoys is very slow in Toshiba nb200, nb250 and nb500 notebooks.

However, if I open etoys from squeak it runs fine.

What do you mean with "open etoys from squeak"? What are the two ways you launch Etoys?

[Josep Pujadas-Jubany (jpujades)]

etoys is a squeak VM, http://www.squeakland.org/

So, if I open squeak I have a menu with all my VM, etoys included.

And etoys runs much faster (at acceptable speed) when is launched from squeak.

Perhaps the problem is the same as described at:

http://tracker.squeakland.org/browse/SQ-400

I have a desktop 64 bit machine with 12.04 too and it not happens. But it is a fast machine, another hardware...

Etoys is a Squeak image, not a VM. The Squeak menu shows you different Squeak images. Anyway ...

Here is how to find out the difference. Start Etoys both ways, and note the options used typing this command in a terminal window:

ps x | grep squeak

On my system I get this:

Running via "squeak": -mmap 1024M -nomixer
Running via "etoys": -encoding UTF-8 -vm-display-x11 -xshm -vm-sound-oss

So these are totally different. For me, "etoys" works much better: sound works, and it's using the "Etoys" directory to store projects.

You may try to remove the "-vm-display-x11 -xshm " options, or add the "-mmap 1024M" option by editing the VMOPTIONS line in /usr/games/etoys. One of these should give you the same performance. Please report back with your findings.

Bert,

Works fine removing "-vm-display-x11 -xshm"

Many thanks!
