Hello guys,
Does IBM promise any response time or SLA? I mean the max time it takes to move a message from put queue to get queue. I know it depends on how many hops it takes before reaching the destination and also on network, but is there any standard number (? milliseconds) IBM gives? I'm just trying to find a way to check if the response time I'm seeing is good or if I need to tweak something to improve the response times.
Thanks for your time. |

IBM Publishes performance reports. I don't think any of them are any sort of 'promise' but they give you a pretty good idea of the kind of throughput you should expect.
One link you could try is http://www-01.ibm.com/support/docview.wss?uid=swg27007150, there may well be others.
Cheers,
Paul.

Sigh.....
I don't get it. I guess I'm officially old.

On a slow or contended machine, local queueing will be slow.
On a high-latency network, remote queueing will be slow.
If you are doing persistent messages, and your disk is slow or high latency (eg. mounted from an NFS device 1000 km away) then your persistent messages will be very slow.
If you are doing persistent messages outside of syncpoints, they will perform I/O activities while certain locks are held, meaning your other apps will be locked out from that queue, making the queue look slow.
In short, performance of MQ is very dependent upon your implementation.
No-one will be able to predict the numbers you will get in your particular environment - but maybe a consultant could help you design and order the right things to make it fast enough for your business. |
