Hi, While looking 'topic manager -> usage -> active durable topic subscribers' usually records are like 'clientId@routername$durablesubscribername' . That clear, but what does mean records like 'router1234$durablesubscribername' and 'router1234$messageForwarder' ? And about perfomance. I'm useing 2.1.3 and would like to know, ca. how many clients one router could handle? If there is too many clients for router then how does it show out, it slows down for sure, but is it possible that if theres about 10 receivers and one publisher, then publishing one message takes 1/2 sec and more clients couldn't log in. What is the normal perfomance for SwiftMQ? Thanks in advance, Hardi    More>>
