Execute multiple cURL requests at the same instant

Using shell or BASH, how can I initiate three http requests using cURL at exactly the same time?  I want all requests to be initiated at the same time.  No response is needed.
curl -s --request GET 'http://www.example.com/?q=1' >/dev/null
curl -s --request GET 'http://www.example.com/?q=2' >/dev/null
curl -s --request GET 'http://www.example.com/?q=3' >/dev/null

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

You may need to create an script file using any editor, then chmod 755 that file with the following contents:

curl -s --request GET 'http://www.example.com/?q=1' >/dev/null &
curl -s --request GET 'http://www.example.com/?q=2' >/dev/null &
curl -s --request GET 'http://www.example.com/?q=3' >/dev/null &

Open in new window

Note the "&" at the end of the command.

This does not guarantee exact concurrent execution but gets close.
