I was wondering if there was some hidden method in the kernel configuration or in sysctl that would allow me to turn off kernel level filesystem cachine for a specific filesystem? The reason I want to do this is because I have one very large ccd0c filesystem that is accessed randomly but at a very high frequency (both read and writes). Anyway, I also have system disks with the programs and such that are run in order to process the data on the ccd filesystem. The problem is as I am running these programs I am noticing that I have a .5 MB/s access to the system disk even though I am only calling one or two sub-programs. Anyway, I believe that is because the ccd0c filesystem is being used so much it is exausting the cache. Thanks in advance for your help. -todd To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-fs" in the body of the message
