I've been thinking about an optimization for the readahead process which Ubuntu uses to pre-load files that are necessary for booting into the Linux cache. I think one remaining bottleneck may be the large number of disk seeks that are still necessary when those files are scattered around.
What do you think would be necessary to prescribe the order of those files, and arrange them physically on the disk contiguously and in that order? A more extreme, more portable way of doing it would be to put them in a tarball, and readahead could read from there instead (most of the time). But this idea has its problems. ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
