> We constantly perform inserts to a collection with 13 indices and 16 basic types fields. On a Dell notebook (XPS 9343 i7 2015 8gb with SSD) running Microsoft Windows it is 10x faster than in AWS running Linux. I don't think the OS is the main issue. Does your Dell machine has exactly the same data files as the aws instance ? As the size grows index grows as well. Also you have not mentioned how many mongo instances in the cluster. One easy way is, you could separate the index and data directories into separate volumes, think this is only possible in wired tiger though.
