accelerate php execution

On the page? <[login to view URL]>, click on "Programme libre" in the second thumbnails bar (below "Séances", not aside), go to the session "sample" (number 215 at the bottom of the page), then click on the "Editer" button. On the last box, there is an area named "Ajouter un événement". Type "trial" in the "Nom" box, then click enter. When using chrome, the process takes 18 seconds, I want it to last no more than 2. Php files involved are attached. ## Deliverables 1) The fix must first be made on a test website of yours, and I must be able to check that it works properly there. 2) A document with the major changes you've made must be sent to me once the fix is made on your test website. 3) No change on [login to view URL] will be made without my written approval on rentacoder. 4) The maximum delay for the given task to be completed must be good on [login to view URL] and not only on the test website.
