I do not think Windows OS had anything to do with this since online trading (as the name implies) is not a fat desktop client based application. I do not want to even speculate as what the problem might have been, but I can say that whatever the problem was, it had something to do with network trafficing and/or server capacity. However, you brought up a good point, and in my opinion, online trading is a perfect example of a thin client/server centric application based model, where the database and the business logic behind processing the data is sitting on one or more cluster of servers. In order to provide a better performance and greater capacity, companies such as ETrade and National Discount Brokers (which by the way a major portion of its on line trading program is all written in Java) require stronger and more pwerful servers to handle the demand. This means nothing but great news for companies such as SUNW, ASPX, HWP, and IBM. Regards, Addi Jamshidi

If any broker has not equipped themselves to scale for peaks in load, (for system capacity or just link bandwidth) they will have trouble. They also need to understand the capabilities/limits of whatever system they have. The Microsoft Web pages do advise using NT 4.0 only as "departmental" level machine and UNIX for "enterprise"level. (Yes they actually say that) They claim NT 5.0 will be ready for "enterprise" level scalability.
