Harald Welte laforge at gnumonks.orgHi Thomas, in case you'd like to add it to your benchmark results, below is a run of trx-bench on a Debian stable (jessie) system on a G-T40E CPU @ 800MHz. What I find surprising is that it appears to be comparable than the Atom D2500 @ 1.86GHz, despite the Atom running at twice the clock rate... More details see attachments.
