Yes ,I have test again with same entironment but to use singleton
IndexSearcher.the performance
has increased. there 100 concurrent user request use different keyword ,and get
60 TPS(2 TPS before).
and now the bottleneck seem to be CPU,and the CPU using approach 100%.and both
RAM(using 70MB average),
HD using as normal.

Could I consider that as long as I have a larger capacity RAM ,and I
will get a good performance.

I don't understand " for disk-cache" meaning very clear.Could you please
explain it again.Thanks a lot!(does't cache on RAM?)
does warm-up == cache?
how many docs do lucene will be cached default?and could I control the cache
size?
I am new to lucene ,maybe my questions looks not professional.
forgive me.
