Well, this is true for _all_ WMS servers. You might not notice that factor with you WMS server if the per-request overhead is rather large compared to the actual rendering and image encoding.

But, there is no need for caching if you already have a fast WMS server. You can either disable it completely or from a specific level on (use_direct_from_level). You can use this if your WMS doesn't have to render much data in higher resolutions.
