I'll get more but it had worked fine in the past.

Thanks.

I'm having a similar problem. I put an order in the DOM (Static) and the order hangs for a few seconds before filling. I don't see large CPU usage, but I hear alot of hard drive chatter. I'm using a P4 3.0 ghz, 3 GB RAM. My hard drive only has a 2 mb cache, would upgrading to a 16 mb cache help with this problem, or is it processor related? It just seems like a hard drive issue to me. Thanks.

This is a problem likely on the very first order placed? It is a RAM limitation on your PC and NT will swap to disk for virutal memory access. To resolve, you can add more memory, reduce the number of applications running or place a dummy order as soon as you start NT.

Ray,

No, I always place a dummy order first. I have 3 GB of RAM, and this occurs even when NT is the only thing running on the machine. I just ran a thread at Elitetrader about this problem, and others have experienced it also. It seems you need a new powerful Core 2 machine to run NT 6. The others all said they had P4's with at least 2 gb ram and had the same problem. I jsut wondered if you think a Hard drive with a much larger cache (16 mb) might make a difference, or should I upgrade my machine? I just upgraded from 1 GB of RAM to 3 GB and still have this issue. Thanks.

Then it must be something on unique PC's that can cause this that we are not familiar with. We run many sub-powerful laptops in the office without issue so I don't believe that you require a powerful Core 2 machine but of course, there must be something on your PC that is conflicting. I wish I knew more.

Sorry I could not of been of more help.

My disk drive only has 2mb cache. Would a newer drive with 16mb help?

I am not a hardware expert so I can not give you a professional opinion however, I would think that would have a positive impact.

Thanks Ray!
