Quick Performance Monitor is an easy-to-use performance monitoring
utility with both auto and manual log modes. Log files are
automatically maintained with time stamp appended to each log file name
and each log record is also time stamped. Comments can be attached with
log data when logs are created in manual mode, which provides great
flexibility when generating log files. You can easily plot the logged
data into Excel spread sheet file to see the trend of recorded data.
Quick Performance Monitor can log all performance counters and objects
that Windows Performance Monitor provides, and it is much easier to use
and much more flexible. Two default settings are dedicated to measure
memory leak and memory fragmentation. Quick Performance Monitor will
make you much more productive in the process of monitoring software
performance."
