We made a significant change how large multipage web-to-print templates are handled at the back end. It was a bit of a weak spot for us. For example a 12-page web-to-print calendar was too slow as the user progressed through the page. Not any more. There is no difference processing page 1 or page 12 or page 20.
PDF generation got a wee bit faster too.
Time to get serious about web-to-print calendars. Let us know if your web-to-print templates are still not fast enough or simply time out. We will try to make them work.
