Slowness may come due to high memory consumtion on restricted hardware. If you have enough memory to run the virtual machine and bridge the output of the sage VM to the host browser you have almost no speed penalty. Of course in a real world use case with 3-10 year old computers and limited bandwith/memory/diskspace big VM's can become problematic. If you want to develop in sage then maybe the best way to go is a big image. In other cases of just using sage, maybe it is better to use compressed images. @volker braun $ du -sh Sage/ 5.2G Sage/ When I spoke of 700 MB virtual machine I meant the data in a compressed filesystem (e.g. Squashfilesystem with estimated compression rate of 3.5) like most live distributions use. I also removed some files (e.g. docs) from the full sage distribution to make it smaller. Docs can be stored directly in the windows filesystem. This would also mean that such a small version is not perfectly suited for developement (although it can be done), but well suited for just "use" like teaching. I developed and tested on restricted hardware (e.g. old desktop with 1 GB memory, 2,2 Ghz dual core Processor). I know this topic has been discussed before and it was decided to ship the full blown version as the the official sage VM. Still it is my opinion that a small image with an optimized userinterface would be the best use of developer hours and skill to improve the "sage on windows experience" for new users and students. With the exception of using the Cloud, of course. Cheers emil -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
