It's not just U2 that likes to have multiple spindles. Any disk intensive processing activity will benefit by having the load split accross multiple disk subsystems. This goes for Oracle, DB2, Microsoft SQL Server, UniVerse, email systems, etc, etc.
Think about it, if your writing an index on one disk and the data on another you are able to do two writes at the same time. Whereas with one disk, the writes will be stacked up and done in sequence.

A few comments: First, using a symbolic link (ln -s) will cause every OPEN to have to read twice .. Once to read the link, and once to read the actual file .. If the goal is to use many spindles, why not just use unix LVM or RAID to stripe a logical "disk" across multiple physical disks? Last one: I've always heard that U2 needs multiple disks for best performance, and I've seen this empirically, but I've never actually heard a good explaination of WHY this is the case .. Any ideas? -CHuck ------- u2-users mailing list [EMAIL PROTECTED] To unsubscribe please visit http://listserver.u2ug.org/ ------- u2-users mailing list [EMAIL PROTECTED] To unsubscribe please visit http://listserver.u2ug.org/
