the downside is that you now add extra costs (seeks :) which.. well readahead was trying to avoid. So if this is going to get used massively it's less certain things will gain as much as before...
I'm not saying use it for everything.. im just saying lets make sure that the default items we have now in the readahead config actually stay in sync with the libraries on disk so users can derive consistent benefit from it over time. My current favorite example is firefox. The libraries are listed in the default readahead config..but now that firefox has seen an update, the listings are no longer in-sync with the files on disk.. because the library locations are in a versioned directory tree...so firefox won't get a readahead boost on an updated system. I understand the seek time issue associated with doing readahead willy-nilly, so if you can think of a way to centralize a default config and prevent out-of-sync conditions like we have with firefox at the moment I'm all ears. Please go ahead and take a lot at the listing in default.later and see if anything else besides firefox is currently out of sync on an updated fc6 install. -jef -- fedora-devel-list mailing list fedora-devel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-devel-list
