The performance aspect could be hard to estimate. Each feature has some cost, we can document what's expected hit but various combinations and actual runtime performance is unpredictable. I'd rather let the tools do what the user asks for, as we might not be able to even detect there are some bad external factors. I think that 250 snapshots would perform better on an ssd than a rotational disk. In the end this leads to the "dos & don'ts". -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
