Detailed Description

Macro for checking the timing (speed) performace of the two different trigger decoders.

This macro is used to check the timing (speed) performance of the existing offline decoder for the trigger DDLs and also for the new high performance decoder. It can be invoked as follows:

$ aliroot .L $ALICE_ROOT/MUON/macros/MUONTimeRawStreamTrigger.C+ MUONTimeRawStreamTrigger(filename, maxEvent);

where filename is the name of a file containing the raw data, or alternatively the directory containing rawX (X being an integer) paths with the raw DDL data. The maxEvent value is the maximum event to process (default set to 1000). Thus the macro will time the algorithm for all events in the range [0 .. maxEvent-1].
