--- Comment #3 from Gabriel Wicke <gwi...@wikimedia.org> ---
Varnish actually transparently decompresses stored compressed content and
strips the supplied Accept header in its backend request. Since mid-November we
always return compressed content, and Varnish stores it in compressed form for
a much better hit rate. So the impact is not as high as I thought:

1) it causes some extra CPU load in Varnish for decompression

2) it results in a larger network transfer on the internal network

Both have a very small performance impact. The Parsoid Varnish is basically
idle CPU-wise and the internal network is fast.

Lowering the priority to reflect this.
