[sage-support] Re: Notebook server very slow. What are typical bottlenecks? I have ver5.2 and 1Gb RAM
I have a Xen Ubuntu Linux 1 Gb RAM virtual machine from a provider called Linode. I am running a notebook server on that virtual machine for my classes... even with only a handful of students hitting it at the same time it slows to a crawl. Is getting more RAM the only solution? How much do you need for 10 people to be able to hit the server all at the same time comfortably? cs On Monday, September 24, 2012 8:31:16 PM UTC-5, kcrisman wrote: On Monday, September 24, 2012 8:32:23 PM UTC-4, Chris Seberino wrote: Notebook server very slow.

Re: [sage-support] Re: Notebook server very slow. What are typical bottlenecks? I have ver5.2 and 1Gb RAM
I'd go for several 100M of RAM each, likely 0.5G to be comfortable, plus some memory for the OS and server itself. Throw 4G at it and it should behave much better, 8G and you should be good to go. Something like https://github.com/jasongrout/sage-forker would likely greatly reduce this requirement.

Linode charges $39.95/month for your 1GB machine. For a 4GB machine, which would be more likely to work well, you would have to pay $159.95/month. My plan with http://salv.us/ -- which I'm working hard on right now -- is to buy a bunch of hardware (mostly done), host it at UW, write much better more efficient software to make Sage (highly) available through it, and provide enough guaranteed resources for a class like you have... for *substantially* less than $159.95/month, since the monthly hosting and network fees I have to pay at UW are super-cheap.
