> 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.
