So, a different scenario, then: Sometimes I need to log stuffs (via ULOG) or do a tcpdump. Will JFS give me additional benefit to ext4? Or should I just stick with ext4?
Simplest performance gain for appends is to drop atime/dirtime from the file or filesystem. It's a fairly common practice on database servers though the gains are relatively minor. I'm not sure how much it would affect logging, but it would be fairly easy to test.
