Running 3 raided SSD drives on my home workstation . . . seriously considering upgrading to one or more raided hyperOs DDR2 Ram Disk Drives. The write latency is nasty on compile time.
- ChuckMcM 15y agoCurious about this, is it RAID-0 for speed or some other variant?

- keithnoizu 15y agoRaid 0, Although I've heard something or other about a larger performance gain being realized by other raid configurations.
- moe 15y agoAre you sure writes are your bottleneck there?
- keithnoizu 15y agoYes. Large code base, large number of intemediary files and bin places. Compiling itself is an issue of course also but i'm already on a fairly high end i7 chip with tri channel ddr. More cpus or faster cpus would be nice but I'll take a faster hard drive over processor speed any day.
- justincormack 15y agoWhy dont you compile on a ram disk then? Its not like you need to persist the intermediate files...
- dexen 15y agoGive NILFS2 [1] a try. It's log structured so the writes do not cause overwrites of filesystem metadata, directories nor files. I have a very old, very slow SSD extracted from Asus EeePC, in an auxilliary computer; NILFS2 makes it crazy fast write-wise when compared to XFS and ext4.
