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?
Hmmm...get more ram :)
Windows 64-bit upped the default file system cache size from 1 gig to
1 terabyte. Your feeling the awesome effects of that upgrade I think.
There is an API call ( SetSystemFilecache() ) to override this - so
perhaps code up a C app to set it before running your Lucene app?

You may actually be able to do it from the registry as well:

havn't confirmed)
Info showing the change from 1 gig to 1 terabyte:

You just want to set it to a certain percentage of what you got -
leaving enough to do whatever your lucene app needs to do.
Found a great page about the problem using Domino:

They appear to have compiled all the little bits of info that I have
seen elsewhere, and describe the problem being fixed just as you did.
