Lets see -- 4.9 to 5.2 MBytes/sec thru the system averaging over 24 hours. Yeah, no problem.
Give the system a decent SCSI RAID subsystem optimized for reading, perhaps up to 10 MB/sec thru several controllers each.
Then distribute the load over 12 busy hours, and you get the record result without needing anything really spectacular. (Except that the 100Mbps network interface is saturated for that half a day..)

Not by a public server, but with a long-term (15-90 minutes long) tests.
It was a laboratory test running our in-house benchmark over HTTP, and my workstation clocked 600 HTTP transactions per second for about 90% of the time running at the peak performance. (quite good result with early 2.1 kernel, dcache was a brand new thing, etc.. All this over a 100BaseTx switched network..)
I don't remember what we clocked as Mbps rates during those runs, though... Propably very close to my single SCSI-disk random read performance, about 5 MBps.
