     Regarding the speed of simulation, the rough estimation is as follows. The distributed simulation module is slower up to
-    15-40 times in comparison with the sequential aivika [2] simulation library using the equivalent sequential models.
+    12-30 times in comparison with the sequential aivika [2] simulation library using the equivalent sequential models.
     The estimation has dramatically changed after started using another more fast pseudo-random number generator by default,
-    which made the sequential module even more fast. The lower estimation is likely to correspond to complex models. 
-    The upper estimation will probably correspond to quite simple event-oriented and process-oriented models, where

     Note that you can run up to 7 parallel logical processes on a single 8-core processor computer and run the Time Server 
     process too. On a 36-core processor, you can launch up to 35 logical processes simultaneously.
