"It depends." [tm]. CPU these days are way faster than hard disk throughput, even when several are striped. You're link said CPU preformance *could* degrade if the performance profile of the box is CPU-bound. If you have a file server with most of the files stored there have high compression ratios (e.g. documents, x-Base databases, text files like source codes) then you'll probably see the performance boost. On servers were you have more pre-compressed files (like AVI's, JPEG's, and gzipped tar files) than documents/text files you may even see some slight performance degradation. _________________________________________________ Philippine Linux Users' Group (PLUG) Mailing List http://lists.linux.org.ph/mailman/listinfo/plug Searchable Archives: http://archives.free.net.ph
