For disks (as in conventional 10.000/15.000 RPM harddrives), IO is clearly the bottleneck for us also. As for Flash-SSDs, we've tried 2 * MTRON 6000 32GB RAID 0, 2 * SanDisk 5000 32GB RAID 0 and SanDisk something (64GB model) both as single drive and 4 drives in RAID 0. However, the performance-observation only goes for querying the indexes. For building, we haven't performed any substantial tests for RAM and for Flash-SSDs vs. harddrives, only the newest SanDisk gave any noticeable increase. One important observation with regard to updating is that our setup with SSDs requires a lot less warmup-time as compared to conventional harddisks. This allows for shorter delays before new content is visible. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
