Greetings, I have a situation where I am reading large quantities of data from disk sequentially. The problem is that as the data is read, the oldest cached blocks are thrown away in favor of new ones. When I start re-reading data from the beginning, it has to read the entire file from disk again. Is there some sort of sysctl which could be changed to induce a more random expiry of cached disk blocks? Wouldn't it seem logical to have something like this in place at all times? thanks, sh To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
