All these are important to selecting the best method of getting optimal I/O. There is no one perfect filesystem/raid level for everything.
Since you are using only a 400Mhz processor I think that reiser3 may be out of the question. It uses a lot of CPU and gets great performace, but if the processor can't keep up then reiser loses a lot of performance. Also any Device Mapper layers will slow you down a bit. I user LVM and love it, but if I really need maximum raw throughput I'd look to hw RAID or sw based RAID (if my system is up to that). For filesystems it just depends on your needs. If you want high sequential reads/writes then JFS and XFS are particularly good. If you need an all around performer, random reads/writes with good sequential throughput then ext3 and reiser (see above note on reiser). Reiser is also the best at purely random access especially with large directories (1,000s of little files). To be honest if you just go look at the filesystem howtos and filesystem comparisons (use google luke) you won't go wrong. They are all up to the task as long as you know a little bit about what your workload is going to look like. -- Zac Slade [EMAIL PROTECTED] ICQ:1415282 YM:krakrjak AIM:ttyp99 -- gentoo-user@gentoo.org mailing list
