By the way, I guess this isn't as effective if you only have one or two processes blocking on reads - won't they have only one outstanding request each at any given time? Readahead notwithstanding, has anyone tried to make apps that need to read lots of small files, read each in a separate thread simultaneously to maximize the elevator benefits (thinking especially about GConf here - AFAIK it's currently serializing concurrent requests)? Relatedly, I'm packaging sreadahead in devel:playground:fastboot now - the kernel-source package in there has the requisite kernel patch. -- Hans Petter -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-factory+help@opensuse.org
