Strange issue with Benchmark Class

Hello, I have tried the Benchmark Class on two Systems. A: Sun Solaris 9 - PHP 4.3.2 B: Linux Redhat9 - PHP 4.2.2 The usage of the class is clear, but on Sun I don't have to call $func->display() to get the results. If I do it the results will shown two times. On Linux works it as designed. There I have to call $func->display() for the results. May someone has experienced this as well? Just is this case of Benchmarking. I have compared with my code PEAR::DB and PEAR::MDB. On my tests I have seen that MDB is 20% slower then DB just in the initiation and database connection. Is this normal or does I have such a strange system? Cheers -Peter
