I ran a few quick tests from a few of my machines and looked at the what was being transfered. For example NT 4.0, C:\WINNT\system32\drivers\etc\hosts DNS, WINS, ODBC, no ODBC I guess what I am trying to say is I could get results that did not make sense from MS OS to MS OS depending on OS, ODBC, configuration, patches... Even if I had everything set the same they they did not seem to be constistent. Sniffing to see that what was sent was really the same was the only way. To make things more uniform I set visionfs on my SCO/Caldera Unix Box be the primary WINS server. I have a local DNS for my test setup. Make sure every machine has it's own "hosts" file that is exactly the same. Make sure all MS of the same type are configured and patched the same. Make sure I have the same configuration for mysql clients, server's, make sure database all have good index's,... Then and only then can I get the same results from each MS OS, they do very some between them. Also check your network drivers and settings on the SCO box. I have seen some strange behavior because of HW, configuration, routing,... Not all ms OS's are the same. I have seen some pretty strange things with them. I think you need to get out your sniffer and look at what is really going on. It may be just how MS does things from one OS to another. Then again it may not. Till you know that things are exactly the same, you never really know. > All of these networking issues would affect general query performance. > However it does not explain the erratic (yet reproducible) nature of how > different queries perform badly, or well, depending. That is what I thought till I got out a sniffer and looked at what was really happening. I was supprised to see the differences. When they did the same thing I got similar responses. What do you see from your programs on the server. Do you see the same differences?
