Sending in 25 orders per sec w/ the sterling API

Sorry none of this is helping.

If you make a new program that doesn't have your strategy and just sends 100 orders (i.e. limit orders away from the market that won't be executed) -- maybe it is something you can share with others running Sterling and get some insight. I switched away from Sterling a few months ago so I can't test myself.

maybe an idea...

you can also generally get sterling on the phone, and perform each test when they watch your accounts.

see if they can tell you more.

They've been very helpful and have listened to my bitch several times, but they have no idea why I have 1 computer that sends em' fast and 7 others that send em' slow. They have suggested to remove anti virus software / firewalls, and probably 50 other things I can't think of at the moment ...... that I did, but still doesn't work

B,
You have a lot more behind the scenes than you think - but you need to get things even.

First, 7 computers... that's a lot. Start with one computer, fresh build, W7x64, install SP1. If you need a "clean" build you can always uninstall and reinstall SP1 after you remove STI.

Are you running same versions of .NET and are you installing the lower .NET app or relying on the reverse compatability of a newer version?

Are you writing and compiling in 2005, 2008 or 2010?

Are you using the same network cards? Same system memory?

If you uninstall and reinstall your NIC drivers + your STI version + your Excel + your .NET do you get the same repeat results on the same machine or does each machine vary. Can you duplicate results on the same exact machine time after time or do results vary on the same machine?

1) Will try to uninstall SP1 and reinstall. I do have btw
2) Writing and compiling in 2005
3) No Different network cards, however same exact memory
4) I have uninstalled the STI version millions of times, with no results. I'm going to try reinstalling .net and maybe the drivers


*** I do not have however SP1... so I wonder if by installing that I'll have luck

It might be the different network cards.

Try swapping them if you can or adding a different one on top of the built-in one.

It could also be some other hardware component such as video card that is using excessive memory or interrupts.

It could also just be a larger cache in the processor on one machine.

You could try running a series of benchmark programs on the different computers and that may allow you to identify the bottlenecks.

Really, you should have posted this under the hardware section of ET.

Anyway, this is pretty simple, but feel free to send me a bottle of Chivas if this works.

1) Make sure you have exact same hardware on one of the computer that is not working as the one that it is working on.

2) Buy a copy of Norton Ghost and an external usb hard drive. This is something you should have anyway for whatever business you do including trading.

3) Install Norton Ghost on the good computer, and make a full backup to the external hard drive.

4) Restore to computer that is not working.

5) Turn off the computer that is working, see if you can now send 25 orders from the restored computer.

Assuming 2nd computer now works fine:

A) Off the top of my head I can't remember it, but Google how to change the Windows license on the restored computer so it uses the license from the sticker on that computer since you usually can't use 2 copies of the same license.
