-# About
+# sysbench
 
-sysbench is a modular, cross-platform and multi-threaded benchmark tool
-for evaluating OS parameters that are important for a system running a
-database under intensive load.
+sysbench is a scriptable multi-threaded benchmark tool based on
+LuaJIT. It is most frequently used for database benchmarks, but can also
+be used to create arbitrarily complex workloads that do not involve a
+database server.
 
-The idea of this benchmark suite is to quickly get an impression about
-system performance without setting up complex database benchmarks or
-even without installing a database at all.
+sysbench comes with the following bundled benchmarks:
 
-## Features
-
-Current features allow to test the following system parameters:
-
--   file I/O performance
+- `oltp_*.lua`: a collection of OLTP-like database benchmarks
+- `fileio`: a filesystem-level benchmark
+- `cpu`: a simple CPU benchmark
+- `memory`: a memory access benchmark
+- `threads`: a thread-based scheduler benchmark
+- `mutex`: a POSIX mutex benchmark
 
--   scheduler performance
-
--   memory allocation and transfer speed
-
--   POSIX threads implementation performance
+## Features
 
--   database server performance
+- extensive statistics about rate and latency is available, including
+  latency percentiles and histograms;
+- low overhead even with thousands of concurrent threads. sysbench is
+  capable of generating and tracking hundreds of millions of events per
+  second;
+- new benchmarks can be easily created by implementing pre-defined hooks
+  in user-provided Lua scripts;
+- can be used as a general-purpose Lua interpreter as well, simply
+  replace `#!/usr/bin/lua` with `#!/usr/bin/sysbench` in your script.
