VTP reading speed and animations

I use Paraview (latest release) on a remote cluster via VNC and virtualgl.

When I need to make a video from an OpenFOAM simulation, I usually save a bunch of vtp files at runtime along with the associated vtp.series file, then I open it in Paraview and save png images via "save animation" (I finally process the png files via menconder).

However, if I have say 1500 files of 16MB size each, it takes more than 2 hours for Paraview to complete the process and looks like most of the time is spent reading the files.

Is this scenario reasonable? If so, is there a way to speed up the process or is there a better way to create animations?
