It may eventually. The lack of direct I/O may also be an issue, since some of our systems don't have enough main memory bandwidth to support data being extensively touched by the CPU between capture (DMA in) and writing (DMA out). Is the notion that 128K is too small based on directio results ? Clearly with directio, a single thread streaming data will see terrible performance. -r _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
