This is a really strange statement. It does not make any sense.
I'm saying that even a single pair of disks (maybe 4 disks if you're using
cheap slow disks) will outperform a 1Gb Ethernet. So if your bottleneck is
the 1Gb Ethernet, you won't gain anything (significant) by accelerating the
stuff that isn't the bottleneck.
That is true. For the record, this is the size of the uncompressed
tarball:
% du -sh gcc-4.4.3.tar
409M gcc-4.4.3.tar
Expecting close to 100MB/seconds for the data transfer over gigabit,
this may place a cap on achievable performance at around 4 seconds.
The test included bzip2 decompression and it is not clear (without
testing) if the bzip2 decompression increases or decreases the
available data flow to the network.
