Need help about Load testing tools for http-bind of Openfire

Dear all,

I am a developer from Thailand which would like to use Openfire as a Chat server.

Our team can use http-bind feature… but I cannot find any test tools to confirm that

server can support how many number of concurrent users that connected to Openfire via Http-bind port 8080.

So, I need you to suggest me about http-bind testing tools.

Best Regards,

Adisorn Sirisomboon
