 <h3>Compression context</h3><pre>  When compressing many times,
-  it is recommended to allocate a context just once, and re-use it for each successive compression operation.
+  it is recommended to allocate a context just once,
+  and re-use it for each successive compression operation.
  This will make workload friendlier for system's memory.
-  Use one context per thread for parallel execution in multi-threaded environments. 
+  Note : re-using context is just a speed / resource optimization.
+         It doesn't change the compression ratio, which remains identical.
+  Note 2 : In multi-threaded environments,
+         use one different context per thread for parallel execution.
