Subject: [PATCH v4 0/5] unpack large objects in stream
Date: Fri,  3 Dec 2021 17:35:25 +0800	[thread overview]
Message-ID: <20211203093530.93589-1-chiyutianyi@gmail.com> (raw)
In-Reply-To: <20211122033220.32883-1-chiyutianyi@gmail.com>

From: Han Xin <hanxin.hx@alibaba-inc.com>

Changes since v3:
* Add "size" to "struct input_stream" which used by following commits.

* Increase the buffer size of "struct input_zstream_data" from 4096 to
  8192, which is consistent with the "fixed_buf" in the "index-pack.c".

* Refactor "read stream in a loop in write_loose_object()" which
  introduced a performance problem reported by Derrick Stolee[1].

* Rewrite benchmarks in "unpack-objects: unpack_non_delta_entry() read
  data in a stream" with sugguestions by Derrick Stolee[1] and
  Ævar Arnfjörð Bjarmason[2]. 
  Now use "scalar.git" to benchmark, which contains more than 28000
  objects and 96 objects larger than 16kB.
