I have been seeing about 10-15 secs, which isn't that horrible really, figuring the time it takes to get from me to the listener on the other end. As long as its under 15 secs im ok with it, anymore than that seems excessive to me, but then im only a few blocks from the fire station. So when i hear the sirens then a pageout on the Squeezebox i keep in the living room on my feed then it gets annoying, but its still manageable overall.
One server loaded too heavy perhaps? Seems like now that you moved a bunch of people around my feed has about a 5 sec delay tonight, was longer for the last week or so.
