I tried to see how much beating CouchDB can take. So I installed it on a modest box (1.8GHz, 512 MB RAM, Debian) and started at 12:00h pouring data in it. At about 22:00h I asked for the computation of a simple view while still dumping data into it. At that Time it contained about 400.000 Documents of with about 10 % contained an Attatchment. DB size was on Disk was about 8 GB.
And an hour later (now) I can’t reach the box anymore.
