-We tested the speed of the extractors by running them on a Intel\ Pentium\ 4 CPU, 
-2.4\,GHz machine at Barcelona and measured 
-the number of events executed per seconds. The results differed by about 20\% from one try to another (on the 
-same extractor), but in general, the differences between the extractors are much bigger than the intrinsic fluctuation.

+We tested the speed of the extractors by running them on an Intel\ Pentium\ IV, 
+2.4\,GHz~CPU machine at IFAE and measured 
+the number of executed events per seconds. This was done using the CPU-time measure features which incorporates each task in MARS.

+The results could easily differ by about 20\% from one try to another (using the 
+same extractor), but in general, 
+the differences between the extractors are much bigger than the intrinsic fluctuation. 
+Table~\ref{tab:cpu} shows the obtained results. The numbers in this list have to be compared to the 
+I/O speed of about 400~evts/sec. of the {\textit{\bf MRead}}-task which performs the reading 
+(and de-compression) of the merpped root-files in MARS. Thus, for time being, every extractor being faster 
+than this reference number does not limit the total event reconstruction speed. Only the integrating spline 
+extractors lie below this limit and would need to be optimized further.
