 ### Key-Value Operations Performance
 
+The following benchmarks measure single-operation latency across different key and value sizes.
+
+#### Sequential Insert Performance (μs)
+
+| Value Size | Key Size (bytes) ||||
+|------------|-----------|-----------|-----------|-----------|
+| (bytes)    | 8         | 32        | 128       | 256       |
+|------------|-----------|-----------|-----------|-----------|
+| 8          | 16.57     | 15.60     | 16.19     | 16.61     |
+| 256        | 16.44     | 16.21     | 16.82     | 16.60     |
+| 1024       | 17.71     | 18.12     | 18.01     | 18.17     |
+| 4096       | 25.47     | 26.67     | 26.92     | 26.55     |

+#### Range Scan Performance
+
+| Number of Keys | Key Size (bytes) | Value Size (bytes) | Latency (μs)
+|---------------|------------------|-------------------|--------------|
+| 100           | 4 (u32)          | 100               | 7.01         |

+### Concurrent Operations
+
+#### Multi-threaded Insert Performance
+Configuration:
+- Key size: 16 bytes
+- Value size: 32 bytes
+- Dataset size: 5MB
+
+| Thread Count | Latency (ms) | Throughput (K ops/sec) |
+|--------------|-------------|----------------------|
+| 1            | 1,055.6     | 94.7                |
+| 2            | 739.3       | 135.3               |
+| 4            | 589.8       | 169.6               |

+All benchmarks were performed on [system specifications] with:
+- Durability: Eventual
+- Disk persistence: Enabled
