Thanks Michael. I also thought about disk performance after I sent the email but is good to have a confirmation that is unrelated to community/enterprise edition. Still, apart from the import tool, I will appreciate if you could clarify me what does it mean that the community edition "scales up to 4 cores"? Having more than 4 cores just doesn't help to the community edition or it could actually yield a worse performance? What about available memory? more is always expected to be better?
