# ROOT Version 2.23 benchmarks on various machines

This file reports results running the ROOT tutorials on several machines in the following way.

         cd $ROOTSYS/tutorials
         root -b -q benchmarks.C
         cd $ROOTSYS/test
         stress -b 30

We have taken an HP 9000/735 99 Mhz to be equal to 27 ROOTMARKS. A ROOTMARK should be more or less similar to a CERN unit.

To be included in this list, the two benchmarks must be run and the results annotated with the hard/soft parameters of the machine sent to Rene.Brun@cern.ch. Because the stress test is I/O intensive, it is important to indicate the disk configuation of your system. Please do not send benchmark results for a configuration already in the list. Only results run in the above configuration will be accepted.

The two benchmarks above are a minimum configuration benchmark. A more solid benchmark requiring about 500 Mbytes of free disk space can be run to test more realistic I/O situations and also to compare the performance of the CINT interpreter to the native compiler.

         cd $ROOTSYS/test
         stress -b 1000
         root -b -q "stress.cxx(1000)"

    The following rootmarks were generated on an SGI L1400 server.
    A quad Xeon 500Mhz system with .5 Megs L2 cache and .5 Gigs of
    memory. Steve.

    Results of this benchmark are overestimated because not run in batch mode
