    Description

      Build tested: a1.0.2-1

      I did cpimport loading test and compared the results from a1.0.1. a1.0.2 is about 27% slower. This new test was done on an even more powerful AWS instance.

      I don't know what caused the slowness yet and we need to investigate.

      a1.0.1 was tested on instance type 4m.2xlarge
      a1.0.2 was tested on instance type 4m.4xlarge
