Pierre Salagnac updated SOLR-18157:
-----------------------------------
Environment: (was: During massive indexing, I noticed GC on
client/SolrJ was a top contributor in performance bottlenecks.
A lot of time is spend in method {{JavaBinCodec.writeStr()}}. It seems we
allocate an internal buffer much too often. For a given indexing batch, each
time the provided string input is larger than the previous one, we allocate a
new buffer with the exact same size as the current input.
If we are very unlucky and each string is one char longer than the previous
one, we allocate a new buffer for each string!
We can easily reduce the number of allocations by increasing buffer size
exponentially.)
