It takes about 30seconds to connect. #4

This tool is cool but it takes about 30seconds to connect to EC2 instance. I tried to connect to same EC2 instance using mssh on same laptop and I was able to connect to the same EC2 in less than 5seconds.

Oh, that must be frustrating! To help debug, can you try connecting with the flags ssh -vvv ec2-user@..., paste the output here and tell me which lines it "slows down" on? That can help debug where the issue is.

Here is debug output.
