Should it maintain 53K regardless of nodes? nodes reads/sec 1 53,000 2 37,000 4 37,000 I ran this test previously on the cloud, with similar results: nodes reads/sec 1 24,000 2 21,000 3 21,000 4 21,000 5 21,000 6 21,000 On Mon, Jul 19, 2010 at 2:02 PM, David Schoonover < david.schoono...@gmail.com> wrote: > > Multiple client processes, or multiple client machines? > > > I ran it with both one and two client machines making requests, and ensured > the sum of the request threads across the clients was 50.
