What Filesystem tuning options are there, or any suggestions, to reduce the amount of seeking going on when N files are being created and written to at once. I have N machines, each one opens a file, writes out a chunk of data, then closes the file. Unfortunatly, because all 50 are doing this simultaneously, the data is getting written to disk very non-sequentially (From a per file perspective). Is there any options to UFS (or via NFSd?) to delay writes, or anything of that nature to allow the data to be serialized more often than not? > > What is the inode state that top displays? > > It doesn't really display inode state, that I'm aware of, only process > state? I mean, in top, what is the process state "inode" relating? What is the process blocking on at that point? -Crh Charles Henrich Manex Visual Effects henrich@sigbus.com http://www.sigbus.com/~henrich To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-fs" in the body of the message
