Thank you Sean, I think it would really be good to have this kind of Wiki or point of visible discussion of FreeBSD on AWS. Because there isn't just bad news, there is also good news. I have a very expensive reporting job on my PostgreSQL database. And I have 3 servers now. An older Amz Linux setup which I did a few years ago, another even earlier. I thought my earlier Amz Linux server was a lot faster than FreeBSD that I set up now. But then in my desperation I set up a new Amz Linux where I even got ZFS installed. But, lo and behold, when I did the report generation I found that FreeBSD worked it in 12 hours while the new Linux system took 21 hours. So there is now clarity that while perhaps some read and write speeds may look better on Linux, in something as complex as my database the result can be better on FreeBSD. There may still be ways to improve the Linux setup, perhaps even more than the FreeBSD, but I don't see anything obvious. The good news is that I can now go forth with my FreeBSD solution which is so much nicer to manage. PS: there are still tremendous slowness. Especially using the AWS CLI Python setup is unbearably and ridiculously slow, so sow in fact that I have rather worked in learning how to sign my own requests and issue those AWS CLI operations with my Java workaround. regards, -Gunther
