Is this writing to several files sequentially? Or do you mean bonnie++ writes has about 5-7 files open at the same time, and has written about 1G into each? If the latter (or regardless), I'd try increasing the size of the cache; since you're seeing traffic across the network, I'd suspect you're thrashing. If you feel like sharing a network dump of the traffic when the problem occurs (probably not to the list), we could tell you what it all is. -- Andrew Deason [email protected] _______________________________________________ OpenAFS-info mailing list [email protected] https://lists.openafs.org/mailman/listinfo/openafs-info
