My point is that the PERCENTAGE of load time is a misleading figure and not the one that you should go by. For instance,
I ran P3 profiler on a install of WP where just Organize Series and p3 Profiler were active, and the 2012 theme was active, and just a few series.
- Organize Series responsible for 87% of load time.
- Organize Series ADDED .0905 seconds to load time.
Next test, I ran P3 profiler on OrganizeSeries.com which has all the organizeseries addons along with other plugins (a total of 34), multiple series throughout the site (including some relatively long ones).
- Organize Series responsible for 4% of load time.
- Organize Series ADDED .0252 seconds to load time.
So my point is that the % of load time is misleading because it all depends on what you have running on your site along with Organize Series. The more helpful figure is how much time a plugin adds to the load time and as you can see Organize Series adds not as much time to the load time.
Also, the P3 profiler plugin is a great tool for initial checks on what may be adding unnecessary load time to a website but as you've seen yourself, is only a tool for beginning the search.
