Do you know what your external dependencies look like? How about uni- vs. multi-processor behaviour in your code? Are you likely to be sensitive to substantial performance differences? Multiple network interfaces? Network mobility? Add-in and USB network adapters? Just as a data point for my case, which is an NFSv4 client, there has only been one issue w.r.t. different Macs. On some, the default 128Kbyte read/write data size works fine, but on others, it has to be reduced to 32Kbytes or the read/write performance is very poor. I suspect this is caused by the net device driver not handling large bursts of received packets well, but I don't know for sure. rick _______________________________________________ Do not post admin requests to the list.
