Hello Dennis, Came across your post while catching up on email. I have my MacBook Pro set up exactly as you described but with one small difference - I replaced the OEM 160Gbyte 5400RPM SATA drive with a 200Gbyte, 7200RPM SATA drive. Aside from that I found my MB seems to out perform my 2.8Ghz dual-core desktop PC with identical memory and hard drive when crunching my AB scripts. Note my MB has a 2.4Ghz dual-core Intel uP.

Then allocate 2GB to the XP virtual machine. You can run all the overhead software on the Leopard side and AB on the XP side on different cores. Trading will then be on a small clean XP machine that can stay that way.

Below is what Wiki says about newer models MacBookPro and their ability to FULLY UTILIZE 4GiB of installed RAM.>http://en.wikipedia .org/wiki/ MacBook_Pro. I will appreciate hearing how others interpret what This WIKI article says. Ron D. The current models support up to 4 GiB of RAM, though they ship with 2 GiB included. The memory front side bus (FSB) is still 667 MHz, while the processor's FSB is 800 MHz. The earliest models support a maximum of 2 GiB (two 1 GiB modules or one 2 GiB module). More recent Merom models based on the "Napa Refresh" chipset could have 4 GiB installed, but could only utilize a smaller and sometimes less efficient 3 GiB of RAM. It was inefficient if used as a combination of two different capacity slots (one 2 GB and one 1 GB).[3] When two 2 GB memory modules are installed the "About This Mac" shows 4 GB, but on these models the Activity Monitor applications reports 3.0 GB as the total amount of physical RAM available. Newer models can address and fully utilize 4 GiB of RAM without an issue.
