Thanks for the info. Norbert, I didn't knew about that UI thread handler in Seaside. I'll check that out.

But IMO the current situation is not really a problem. Actual load problems will still be caused by real load, not by idle instances. Anyway, that is what I see on production machines with multiple Pharo instances next to many other processes. Sven BTW, load & cpu usage numbers can be very hard to interpret. -- Sven Van Caekenberghe Proudly supporting Pharo http://pharo.org http://association.pharo.org http://consortium.pharo.org

While decades ago polling was the way to handle native and external stuff this isn't the case anymore. The big problem is that the image has quite some polling actions going on keeping the image eating cpu cycles. Your best bet at the moment is suspending the ui thread. That will spare some cycles. If you use seaside there is even a web handler to suspend/resume the ui thread. Or you can hack the vm to use an event based approach. Norbert

Futures

by phil＠highoctane.be

I am currently experimenting with Pharo on Amazon EC2. I'd like to keep the CPU usage low for when Pharo hasn't anything special to do. At the moment, I see that Pharo uses 2-3% of the CPU when just blinking the caret. Is there a way to get that lower? Even if it means tweaking the VM. The OS is Ubuntu 12 LTS Thanks!

Keeping Pharo CPU usage low: how?

by phil＠highoctane.be

I am currently experimenting with Pharo on Amazon EC2. I'd like to keep the CPU usage low for when Pharo hasn't anything special to do. At the moment, I see that Pharo uses 2-3% of the CPU when just blinking the caret. Is there a way to get that lower? Even if it means tweaking the VM. The OS is Ubuntu 12 LTS Thanks!

Re: [Pharo-dev] seaside 31 configuration not loading

by Diego Lont

Camillo, The official stable version of seaside is 3.0.8, that can be found in the Metacello repo. location: 'http://www.squeaksource.com/MetacelloRepository' As far as I know, this version is in the green. I see that some changes where made to Zinc-Seaside since I last checked â¦ but still. For 3.1 there is still some work that needs to be done on the configuration. I started with it, and Johan did some work on this too, but we didn't finish this work yet. When I have time again, I will try to fix the configuration and seaside 3.1 code for Pharo 2.0. The latest version can be found in the Seaside31 repo, http://squeaksource.com/Seaside31.
