Yes, but it was expected. It's like prioritising code readability over performance everywhere but the hot path.
Earlier in my career, I managed to use Zopfli once to compress gigabytes of PNG assets into a fast in-memory database supporting a 50K+ RPS web page. We wanted to keep it simple and avoid the complexity of horizontal scaling, and it was OK to drop some rarely used images. So the more images we could pack into a single server, the more coverage we had. In that sense Zopfli was beneficial.
