Try this
guide (thanks to gdl) it explains in detail what you have to do to make the remote work. I will add this link to my FP.
edit: i had the "slow response" problem before but that was when i was using CybrDisplay plugin with remote support. Make sure that if you also have the CybrDisplay plugin to update to the latest version to remove this remote support. Maybe it's conflicting with IR Server Suite.. or.. you don't have the latest IR Server Suite files?
