I was reading this article on analysing Linux ext(2/3/4)fs in a high-performance server environment as an appropriate file system.
The idea of the article certainly raised my curiousity and the start of it did pique my interest. I was looking for the answer to this particular question asked early on:
"Can Linux file systems, which I will define as ext-4, XFS and xxx, match the performance of file systems on other UNIX-based large SMP servers such as IBM and Sun?"
Unfortunately, the rest of the information did little to assert the claim that for now (ext3 fs) and in the near future (with ext4 fs), are not designed to support large file systems that are typical with high-performance server environments.
