Our use case is a worst-case read/write scenario. The SSD partitions we use for the DB servers are mirrored software RAID1, which, to my understanding, makes the use of trim impossible. Where we've had performance problems we've always found something else to be the bottle neck, typically a poorly constructed query. (PostgreSQL really, REALLY hates left outer joins) It's possible that we could eek out more performance with a suggested kernel update. If/when we do performance testing on that front, I'll make it a point to submit my results. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Thanks to all for what was a surprisingly interesting thread! Here are my very informal and unscientific tallies. This isn't actual systems, of course; it's counting people's responses, so my ~10 vanilla kernels count as one Stock in the tally below. Stock: 16 CentOS Plus: 5 ELRepo -ml: 3 ELRepo unspecified: 2 Custom build: 2 ELRepo -lt: 1 Stock + ELRepo kmods: 1 Oracle: 1 OpenVZ: 1 No big surprise in the results; most people tend to stay with the stock kernel, but quite a few people use one of the others. I imagine that more people who didn't respond would be more likely to be stock kernel users, so the numbers are probably a bit skewed towards the tinkerers and funky hardware or kernel feature requirements. People's reasons for using a non-stock kernel were also not a huge surprise. I don't recall anyone saying that they use a different kernel just to be recent; in the cases I remember everyone had a reasonably specific reason to use a non-stock kernel. That also makes sense here; it stands to reason that CentOS users want stability, and stray from the path only when stability is compromised by sticking with stock.
