>>Dave, once again, the programs I will be running simultaneously include two web browsers, several Kill Keys, several real time charts, a JAVA based execution software, and several different mIRC chat channels. Would this be too much for '98 to handle?<< Besides asking the question is this to much for Win 98 to handle you should also be asking is this to much for one CPU to handle. I can't answer this question directly but there are some other considerations that can help you answer this question. How much I/O can a network interface card, NIC, handle by itself? That is can a NIC transfer data directly to memory using direct memory access, DMA, or does all data have to be handles by the CPU before it is stored in memory? The answer to this question makes a big difference in how much time the CPU has to spend processing I/O and whether your computer appears to be very sluggish. Spots do you or anybody else know whether a NIC has DMA? If it doesn't and because the amount of I/O you want to process appears to be the equivalent of three 28.8 kilobaud modems running simultaneously on one computer I predict a one computer system will be very sluggish. Spots or anybody else do you know if when running Win NT and a dual processor motherboard if you can control which programs run on which processor? That is can you have all of the web browsers and mIRC channels run on one CPU and all of the programs you use for executing a trade run on the other CPU? Does any body know of any experiments we could run or know how we could simulate a system like Street Walker wants to build so we can better predict the performance of Street Walkers system? Lacking better answers to the above questions I say we can rate our choices as: Least desirable: A One CPU Trading Station and reduce the number of programs you run concurrently. Dual CPU Trading Station. Most desirable: Multiple Computer Trading Station.
