Heavy usage of hosting resources

Hi

We have our wordpress site https://dlharbour.ie (using Events Calendar Pro) hosted with media temple. Over the last couple of months our hosting GPU usage has gone way over our monthly allocation, so we have been looking into why this is happening (as its costing way too mush in extra charges!).

The biggest offender by far is the homepage of https://dlharbour.ie which accounts for 50%+ of bandwidth.

We just ran a SSH command to show us a list of plugins that were hitting the home page and by how much.

dlharbour.ie/html$ strace php5 index.php 2>&1 | perl -ne ‘if (/plugins\/([\w\d-_]*)/ ) { print “$1\n” }’ | sort | uniq -c | sort -n

Here is the list of the top plugins:

11087 the-events-calendar
3556 nextgen-gallery
742 contact-form-7
741 wp-optimize

As you can see, The events calendar is almost using quadruple the resources of the second plugin in the list!

Can you help me to reduce this as all we are doing is displaying a couple long term events on the homepage?

Thanks

Paul
