For achieving more performance we change this new script from uni-threaded to multi-threaded i.e data collection and data analysis operations run in parallel to each other. The mechanism is that when the data is downloaded for 5 monitoring sites a separate thread is created and this collected data is passed to this new thread for analysis operations and at the same time data collection for other monitoring sites is also running in parallel to this analysis thread. The performance or speed results after these optimizations are shown below:
After this we change pingtable.pl to read analysis results from tables instead of flat-files and show these results on the browser. At this point we change pingtable.pl to show only hourly results not daily and monthly results. They are shown when we complete daily and monthly analysis discussed below in this chapter.
