No, I meant a specific thing Jackrabbit is not good: Jackrabbit is a hierarchical storage, like a FS. When you store like 100.000 nodes in a flat structure below one single node (in other words, not some trivial folder structure), then accessing these nodes will be slow (compare a to a filesystem with hundreds of thousands of files in one folder, that will be slow as well). 100 concurrent users does not seem much to me, unless they write like 100 nodes each second per user, but that is ofcourse obvious.
