Amazon Now Serves Files At Sub-Millisecond Speeds

In an AWS blog post, Amazon announced that its Elastic File Systems (Amazon EFS) "now provide average latency as low as 600 microseconds for the majority of read operations on data and metadata. "We seem to be approaching the speed of light, even when taking into account IOPS, throughput, and all other external factors," writes Slashdot reader segaboy81. Neowin reports: Amazon is announcing an enormous increase in read speeds. According to an AWS blog post, EFS read operations have typically hovered in the low 1ms range, but after they "flipped the switch," read operations are now halved. Users can now expect read speeds as low as 600 micro-seconds. I'm not a scientist, but online calculators seem to indicate light can travel roughly 113 miles every 600 microseconds. This begs the question; how close will you need to be to a data center to get this performance benefit? Either way, it's worth noting that this is not a new performance tier. Users of EFS will see this benefit at no extra cost.
