The Domino 8 server has a new memory manager. Note: Used more commonly used to tweak multiprocessor high memory UNIX / AIX / AS/400 machines.
ConstrainedSHM, ConstrainedSHMSizeMB
MEMAddressableMem, MEMAddressableMemSizeMB
MEM_EnablePreAlloc, MEM_EnableSubAlloc

After doing this, you can use the new design and data compression settings (application properties advanced tab - 2 checkboxes).
