4gb ram
Cakewalk Sonar x1 (32bit install)
Focusrite Scarlett 2i2, USB 2.0

Sonar is reporting latency of between 10-16 ms (round trip i think). around 10 if i reduce the buffer to as low as it goes and it was a bit over 16 to start with.
I read about people getting their latency down to as low as 1.5ms and easily around 3ms.

I have also read that you can tweak your PC and/or OS to aid latency issues, but i have no idea what to do for this.

I am using a USB 2.0 port, and I have the latest audio drivers for the 2i2.

Any other suggestions?

Sonar is fast, I love it for midi.
Optimize your pc for sure, it makes a world of difference.

check out a few of these otimizing windows 7 for recording - Google Search

A high quality interface is also key, however, yours looks okay but optimizing and a speedy processor helps the most. I've never been a fan of usb for midi so I don't use it, I stick to firewire and plug into the interface. Seems better to me. If you use usb, be sure to use an external power supply for all your gear that is connected, like keyboard, controller etc. I find relying on the usb power slows everything down.
