It's interesting how much faster your laptop SSD is compared to these high end performance oriented systems. Keeping in mind that the localhost/tls-disabled number is a high bound. (Not singling out Arrow by any means, most others are slower. )<p>I wonder which came first, the petering off of wired network hardware perf improvement, or the software bottlenecks that become obvious if we try to use today's faster networks. 100 Mb ethernet came in 1995, gigE in 1999, 10 gigE in 2002 and gained adoption in a few years.. on that track we should have had 100gigE in 2006 and seen it in servers in 2008 / workstations in 2010. And switches / routers should have seen terabit ethernet in 2010. Today's servers(X) seem to be at about 25 GBe, and with multicore that's just 1-2 gigabits per core.<p>(X) according to <a href="https://www.supermicro.com/products/system/1U/" rel="nofollow">https://www.supermicro.com/products/system/1U/</a>
