13 I have hardware on which I would be more than willing to perform this
14 type of benchmark. Can you provide/point to a repository of files to
15 benchmark, and a set of operations to perform? The obvious being the
16 portage tree itself, with some/all of its history (however much is
17 necessary for the benchmarks to be meaningful), but would require a set
18 of activities to generate a relevant benchmark.

20 For reference, I have a server that is not yet in production, but
21 readying for production in the next few months, running Gentoo, on a
22 raid-5 array of SCSI harddrives. I don't remember the precise
23 specifications off hand, but I could provide them along with the results.
24
25 Would this be useful? Would more/other hardware be necessary useful? (I
26 have access to multiple workstations on which I could run simultaneous
27 tests, causing transactions to become relevant and important, etc etc,
28 and further hardware might be available here.) Hope this can be of some
29 use to you in trying to make this evaluation.
