Coda Hale commented on SOLR-122:
--------------------------------
I can't nail down the query benchmarks -- running the same benchmark over and
over again gives me fluctuations of 20-30%.
I simplified the indexing benchmarks -- now it takes a hash of 1000 records,
adds them in, and deletes them all. It does that 100 times. Here are the
results:
user system total real
REXML indexing: 444.590000 2.740000 447.330000 (549.907248)
libxml indexing: 34.450000 3.650000 38.100000 (138.402562)
> Add optional support for Ruby-libxml2 (vs. REXML)

> Project: Solr
> Issue Type: Improvement
> Components: clients - ruby - flare
> Reporter: Coda Hale
> Attachments: libxml.rb, libxml.rb

>
> This file adds drop-in support for the ruby-libxml2, which is a wrapper for
> the libxml2 library, which is an order of magnitude or so faster than REXML.
> This depends on my SOLR-121 patch for multi-document adds, since the behavior
> of Solr::Request::AddDocument#to_s is different.
> Requiring this makes some tests fail, but for trivial reasons: some tests are
> directly tied to REXML, others fail due to interelement whitespace added by
> libxml2 (which you can't disable via the Ruby interface). Functionally, it's
> identical, and passes all functional tests.
