Review request for Baloo and Vishesh Handa.
By Christian Ehrlicher.

Updated Nov. 5, 2016, 11:37 vorm.

Repository: baloo

Description (updated)

This patch speeds up PostingCodec::encode() by a factor of ~4 by not adding every single encoded int32 to the resulting bytearray which results in a lot of small memcpy operations. The idea is to use a preallocated QByteArray and directly encode the integers into this buffer. This makes the code a little bit more complex but the speedup should be gain enough for this.

Ping! No interest in this patch? Should I discard it?


positoncodectest calculates the same md5sum as before.
