Every boost had its own fragment, nested inside the message fragment that already holds it. With a cold cache, a read and a write per boost plus a read_multi and a write_multi per message: a room page of 40 messages with 120 boosts takes ~410 ms instead of ~290 ms. Redis runs without persistence (config/redis.conf), so every page is cold after a restart. A boost touches its message, so adding or removing one rewrites the message fragment anyway. The inner fragments only paid off when a message with many boosts was drawn again, and there they hid a lookup per booster. The boosters are now loaded with the boosts, one query per message.
