To simulate some of this, you could try using a ramdisk. MSDN has a bunch of items on how to setup a ramdisk (for Win 2k, try here: http://support.microsoft.com/default.aspx?scid=http://support.microsoft.com: 80/support/kb/articles/Q257/4/05.ASP&NoWebContent=1 ) It's not as elegant a solution, but it should approximate the speed of a shared memory solution (minus the filesystem overhead) and should be really easy to test (just a few minutes to install the ramdisk and reconfig your app to use the new drive for temporary space). If it proves to increase your performance, then you could look at the more elegant code based solution. Of course, depending on how large your serialized data is, you might need more RAM...
