Is there any way to store document data in-memory rather than on disk? This way the performance can be increased because of reduced IO.

You can either use attribute fields in combination with fast-search (to build posting lists on top of the data), or consider putting the index on RAM-disks. The most common approach is to use a combination of attribute fields and on-disk index and use SSD drives, though.
Also, for document summaries it is good for performance to have all fields in the most commonly requested summary class be attribute fields.
