Time delay question

I have a project that will have two ways to achieve an action. One using a HUd which will use chat and the other a menu that will use linked messages. What I want to know is if there will be a significant difference in performance between the two. First, would there be difference in the time a script would receive a message sent through chat versus one by a linked message? If so how much? Second, if the Hud chat message was sent to the Menu script that then sent a linked message to a thirt script, how much time would that add to the process?

Probably not what most people would consider "significant", no.
Yes, chat would be slower, but it isn't possible to guarantee a time on that. For most purposes, the time is effectively the same.
Not much.

From a UI perspective, llDialog is going to be more reliable than an interface you build yourself, in the sense that clicking on buttons generated by SL's UI is more absolute. Still, I wouldn't expect problems to come up in either case.

You do have to watch out for the event queue though. What is your script otherwise doing? Is it possible that it could queue up a bunch of events and miss chat or linkmessages?

I'm pretty muchw ith Cat here, I would use the chat though. Just the fact that you need those ressource sucking listens.

Also, link_message and chat do queue up. Last I heard it was up to about 100 requests before they started dropping some.

Thanks for the info. The two message senders are few events, usually only a couple per message.
