And to round out the boxes I have that can be easily updated to current:

sparc10 (SuperSPARC??, 36MHz?? - I don't use this one much)

    before  Pipe bandwidth:  9.80  9.71  9.85  6.32 MB/sec
    after   Pipe bandwidth: 20.62 20.66 20.65 20.61 MB/sec

    before  Pipe latency:   177.9432 177.9208 177.8575 178.7462 microseconds
    after   Pipe latency:   115.9653 119.9508 115.9463 122.0975 microseconds


HP433s (68030, 33MHz)
    before  Pipe bandwidth: 1.71 1.71 1.69 1.71 MB/sec
    after   Pipe bandwidth: 4.69 4.24 4.68 4.67 MB/sec 

    before  Pipe latency:   744.5042 841.9563 728.5992 846.4777 microseconds
    after   Pipe latency:   452.7576 453.0590 454.8244 455.7805 microseconds


DNARD/shark (SA110, 233MHz)
    before  Pipe bandwidth:  5.11  5.11  5.11  5.12 MB/sec
    after   Pipe bandwidth: 22.48 22.51 22.48 22.55 MB/sec

    before  Pipe latency:   809.2607 814.0175 810.4924 811.2817 microseconds
    after   Pipe latency:   677.7733 677.5871 680.2849 677.9899 microseconds

Again, all impressive results.
