Just to complete my report:
The tests I reported in this issue were done with a little more beef in the
documents - I had added about 4 lines from a newspaper article. The result is
that we are only about 4-5% slower using those documents now. However, with
Yonik's original test, with very short docs:
{code}
String[] fields = {"text","simple"
,"text","test"
,"text","how now brown cow"
,"text","what's that?"
,"text","radical!"
,"text","what's all this about, anyway?"
,"text","just how fast is this text indexing?"
{code}
...we are 10% behind. This is a mix of TokenStreams - you can see the
tokenfilters used in the profile pics. This is huge improvement from before -
that was 50-60% slower with this test.
All profiling pics are from Yoniks original small doc test with 100000
iterations.
I'll attach:
before the reflection token stream stuff
after (trunk)
after with this patch
