| Is anyone prepared to speculate whether WMQ v6 on AIX (being 64 bit and using IPv6) would be able to manage more/less concurrent sender/receiver channel pairs than v5.3 on the same machine? Does anyone know enough about the TCPIP stack on AIX to give an opinion? |

How many SNDR/RCVRs do you want?

About 1500 pairs at this stage and possibly more in the future.
I'm trying to get a handle on how many machines I will need to support this many before the performance degrades too much. The channels will be all active all the time although the traffic rate will not be high.
I have seen the support packs and the 6000 channel pairs on AIX and the effect this many had on round trip times. I'm assuming I will get about 1000 per machine when I test although I'm keen to hear of any real experience with these kind of numbers.
I am interested if WMQ 6.0 will bring anything to the table regarding channel performance that is new over 5.3.
Cheers |

If the traffic is not high can you take the performance hit of triggered channels ? |

| While the traffic is not high, it is constant so I don't think the hit of bringing the channels up and down will buy me much. |
