Everything's relative. I won't argue you should turn it off, just that "it's working fine" is relative. Everything works fine right up until it doesn't when you haven't changed anything, and at that point, maybe what was fine before now isn't. It's all subjective. You have to decide what's right for you, and then benchmark the conditions you believe work for you. Maybe those change. If so, hopefully you aren't locked in if your previous choice is now no longer best. -- Derrick _______________________________________________ OpenAFS-info mailing list [email protected] https://lists.openafs.org/mailman/listinfo/openafs-info
