Try InstantiatedIndexWriter/Reader (under contrib/instantiated)?
It consumes more RAM than the RAMDirectory approach, but is faster
performance.

PS -- this sort of question should go to java-user in the future.

Hi,
If I use lucene to execute many search requests at one time, the
io operation will be the bottleneck of the performance.
So I use RAMDirectory to avoid io operation.
But I found RAMDirectory cannot raise the performance much if the
index is big( about 1.2G).
Could anyone give me any advice to raise the performance for
concurrent search operation?
Thanks.
