+## Benchmarks comparison
+
+Here are some [benchmarks](bench-comparison) comparing spdlog vs boost log(1.56.0) on Ubuntu 64 bits, Intel i7-4770 CPU @ 3.40GHz.
+
+The bench writes 1,000,000 log lines to a rotating log file:
+
+#### spdlog vs. boost - single thread
+|library|log lines|threads|elapsed|
+|-------|:-------:|:-----:|------:|
+|*boost*|1,000,000|1|**4.207s**|
+|*spdlog*|1,000,000|1|**0.975s**|
+
+
+
+#### spdlog vs. boost - 10 threads
+|library|log lines|threads|elapsed|
+|-------|:-------:|:-----:|------:|
+|*boost*|1,000,000|10|**6.592s**|
