Please respond
to MQSeries List
I have a customer in Germany, who is displeased with the throughput he is
getting with his client connection to my server in Atlanta. Please see the
encrypt from an email I received from him below.
Relating to our 32Bit-Frame-Relay-Connection between Germany and Atlanta,
I've some more questions.
1. 240KB a minute is the theoretical limit of the bandwidth
2.1 with big messages (e.g. 2397 bytes) we reach following limits:
2.2 from Germany to Atlanta (MQPUT)
2.3 90 msgs per minute => 210 KB bandwidth
2.4 from Atlanta to Germany (MQGET)
2.5 82 msgs per minute => 191 KB bandwidth
3.1 with small messages (e.g. 288 bytes) we reach following limits:
3.2 from Germany to Atlanta (MQPUT)
3.3 160 msgs per minute => 45 KB bandwidth
3.4 from Atlanta to Germany (MQGET)
3.5 116 msgs per minute => 33 KB bandwidth
Now, the customers assumption is that the problem is with the queue manager
in Atlanta, I am not convinced he is correct. I know there is a
communication over head for using an MQ channel. I believe it is just over
1500 K, but I can't find the exact number in the manuals. Does anyone
happen to know what it is?
The customer currently connects as a client, but they do run a full queue
manager. I do believe building them a sender / receiver pair of channels
might help some, but what they are asking is multiple channels. If
bandwidth is the problem, more channel won't help much I'm sure.
Any help would be appreciated
Thanks
