Here is a Geekbench benchmark report for one of these new micro instances: http://browse.geekbench.ca/geekbench2/view?id=287891 . It uses the same E5430 processors as the other m1 instances. CPU performance is about 2x m1.small based on these m1.small Geekbench results: http://browse.geekbench.ca/geekbench2/view?id=241412 and comparable to a rackspace 4GB server I also benchmarked: http://browse.geekbench.ca/geekbench2/view?id=243138.
