Helen,

I think it's already there !

Page 61:
Some General Improvements
O. Loa, D. Yemanov
• Much faster algorithms to process the dirty pages tree
Firebird 2.0 offers a more efficient processing of the list of modified 
pages, a.k.a. the dirty pages
tree. It affects all kinds of batch data modifications performed in a 
single transaction and eliminates
the known issues with performance getting slower when using a buffer 
cache of >10K pages.
This change also improves the overall performance of data modifications.
• Increased maximum page cache size to 128K pages (2GB for 16K page size)

see you !
