comment Amazon VPC NAT performance problems
I enabled direct internet access on one of the servers in the private subnet, and it completed the download task in about the same time as doing it directly on the NAT.

comment Amazon VPC NAT performance problems
@MattHouser I have both t2.medium and r3.large instances in the private subnet, and both types exhibit the same problem. I'm going to try attaching an Elastic IP directly to one of those instances to see what happens with a (more) direct connection.

comment Amazon EC2 VPC: NAT instance download speed performance drop
Thank you. I have spent many hours trying to debug intermittent network performance issues on a new VPC configuration. My private EC2 instances request files from S3, and the requests would frequently stall for long periods (sometimes over 2 minutes). This was easily reproduced by piping a list of URLs through curl. Running the same requests directly from the NAT instance did not exhibit the same problems. Disabling scatter-gather mode on the NAT instance solved the problem immediately.

comment Managing Remote MySQL DB using local phpmyadmin
Although I much prefer the CLI interface, the output from PHPMyAdmin is often much easier to read. If you do end up having to use the CLI, did you know that you can get results output in vertical format by replacing the terminating semi-colon with \G? e.g.: SELECT * FROM mytable\G It's not perfect, but it might help make the output easier to read.

comment Linux (Ubuntu) environment variables, shells and security
Thanks for he answer - please could you expand a little on your suggested solution of creating a configuration for the applications? They are all Perl applications, one is the main web app running under Apache, and the others are utility scripts, some of which can be run as daemons. Are you suggesting that I modify the Perl scripts, as I have done already for the web app?
