One other thing I think we should try is to organize the cache per client address and evict cache entries from clients with more entries first, on the theory that: - There are diminishing returns from keeping huge numbers of entries from a single client: a client that has sent us lots of new requests is likely to have processed replies to the older ones. - We should still try to hang on to a few of the most recent entries from a client that hasn't made any requests recently, because such a client may have just temporarily lost contact, in which case it's particularly likely to need to retry a request, and we don't want its entries pushed out by clients that remain active. --b. -- To unsubscribe from this list: send the line "unsubscribe linux-nfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
