well balanced system
=================
Agree. Here we'll start a performance & load test this month. I've defined a
test criteria of 'qps', 'RTpQ' & worse case according to our use case & past
experience. Our goal is pursuing this criteria & adjust hardware & system
configuration to find a well balanced scalable Solr aritecture.
However, the past discussion of this thread has several good suggestion for
our test. Thanks to all who provides their experience & suggestion.

If you really want to see performance, try external DRAM disks.
Whew! 800X faster than a disk.
As sexy as they are, the DRAM drives does not buy much more extra
performance. At least not at the search stage. For searching, SSDs are
not that far from holding the index fully in RAM (about 3/4 the speed in
our tests but YMMV). The CPU is the bottleneck.
That was with Lucene 2.4 so the relative numbers might have changed, but
the old lesson still stands: A well balanced system is key.
