 description = "This dashboard visualizes Memory Efficiency trends across Valkey versions. It helps compare releases side by side, highlight Memory Efficiency gains from new features. Discover how [our new hash table design](/blog/new-hash-table/) reduces memory overhead."
 methodology = "These benchmarks are generated by starting an empty instance of Valkey for each test, measuring memory usage, then adding 3 million string items of a certain data size, then measuring Valkey memory usage again. We take the increase in memory use, divide by the number of items, and subtract the size of the user data (key and value) to get the extra overhead bytes Valkey uses to track and organize the data. For this graph, we tested every value size from 8B to 128B inclusive, then averaged the numbers for each range in this chart."
