Hm, looks like I've just given a bad advice. It seems that auto-tuned arc_max is based on kmem size. So if you use kmem size that is larger than available physical memory, then you better limit arc_max to the available memory minus 1GB or so, if the autotuned value is larger than that. I think this needs to be fixed in the code. -- Andriy Gapon _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "[email protected]"
