Yonik Seeley updated SOLR-377:
------------------------------
Attachment: fastwriter.patch
attaching patch... adds an optimized unsynchronized buffered writer, changes
some ResponseWriters use of strings to characters, removes buffering of string
in JSON, etc.
Speed differences with *very* large documents:
json: 24% faster
ruby: 500% faster (ruby didn't buffer in a StringBuilder like JSON did)
python: 0% (bottleneck for these huge fields is buffering in the StringBuilder
to see if we should prepend a 'u'... always prepending a 'u' and not buffering
resulted in a ~20% improvement)
xml: 8% faster
With smaller documents, the speedups are likely to be greater because small
writes like value separators would matter more.
If there are no objections, I'll commit in a few days.
> speed increase for writers

> When solr is writing the response of large cached documents, the bottleneck

> a buffered writer implementation that doesn't do any synchronization could
> offer some good speedups.
