windows file system cache

[Robert Stewart]

Anyone else run on Windows?  We have index around 26 GB in size.  Seems file 
system cache ends up taking up nearly all available RAM (26 GB out of 32 GB on 
64-bit box).  Lucene process is around 5 GB, so very little left over for 
queries, etc, and box starts swapping during searches.  I think changing file 
system cache size setting is needed.  Anyone else have same issue?
