Time taken to send a message in Amazon's SQS

How long does it take to send a message with Amazon Simple Queue Service?

Also, I'd like to know how many messages开发者_运维技巧 will be sent in a minute in Amazon SQS?

As of 2007, at least one user got these results:

Looks like 1.5 seconds per read is safe for planning, or 40 reads per minute.
