I had my sights set lower. Our Thumper has four hot-spare drives right now. I'd take one or two of those out and replace them with one or two 80GB SSD's, upgrade to S10U6 when available, and set them up as a separate log device. Now I've gotten rid of the horrible NFS latencies that come from NFS-vs-ZIL interaction. It would only take a tiny SSD for an NFS ZIL, really. We have an old array with 1GB cache, and telling that to ignore cache-flush requests from ZFS made a huge difference in NFS latency.
