I don't know what it would take to run the transmit in parallel. In some cases a response comes back from one of the servers, as mentioned in the comments:
/*
* Even though this is the "sendtomany" routine, we need to decideif the * request should go to all servers, or just a single server. The default * is to send to all servers - but commands that trigger a response can * only go to a single server. * * "schedule" is special - when scheduling an action there is no response, but * when it is the blank "schedule" command there will be a response. So a * schedule action goes to all Xymon servers, the blank "schedule" goes to a single * server. */
Perhaps the feature request should be: try each server once, then move on to the next. Take out of the list any server that responds. Run through the list N times as long as there are servers still in the list.

Well spotted Ralph, Thanks a lot.****
But the code seems to miss something here.****
Shouldn’t it send to both servers at the same time? Regardless of the other being up or not?****
Is there any reason to wait for the first server to answer before sending to the next?****
And even so, the time from the client should be when it is sending not when the sending process starts.****
I really like this feature as it gives me a very cheap and easy “xymon cluster”.****
I discovered this when one of my xymon servers died on me last week.****
I just had to change the http port to see the “backup server” instead.****
Feature request?****
At least we know what is happening and why.****

I just looked at the code (xymon-4.3.10) - the xymon client program has a default timeout of 15 seconds, and retries twice. That's 45 of the 47 seconds delay you're seeing before it tries the second server.****
To answer your original question, yes, that would seem to be the expected behaviour... :-)****
