Change subject: [docs] Add basic advice on setting block cache size ...................................................................... [docs] Add basic advice on setting block cache size This adds a short section to the troubleshooting guide about improving the performance of the block cache. It's fuzzy since the effectiveness of the cache and the efficacy of enlarging it are so workload dependent (e.g. consider a workload doing full table scans vs. one mostly re-scanning a small range checking for updates), but I tried to provide a starting point for users to evaluate their cache size since we've totally lacked any advice on that up to this point. I also added information about the change due to release in 1.8 that servers won't start when the block cache capacity is set too large relative to the memory limit.
