LDview on the contrary can generate superb image quality but at the cost of speed. So my strategy is to use LDGlite during my work in LPub and switch to LDview just before printing/exporting.
It's worth mentioning that (possibly minor) changes in LPub could increase rendering speed using LDView. Specifically, if it asks LDView to render multiple files using a single call to LDView, things speed up some. A test with three random unrelated LDR files gave 4.3 seconds to generate snapshots for the 3 files with 3 separate executions of LDView, and 2.6 seconds with one command line requesting that LDView render all three files. I suspect that if the files were multiple steps of the same source model, the speedup would be greater.
Rendering multiple files is done by using -SaveSnapshots=1 instead of -SaveSnapshot=somefile.png. Then, simply listing all the LDR files at the end of the command line will cause all to be rendered in a single call. This does require that all other command line options be the same, and you have no control over the snapshot filenames. (They'll be the original LDR filename, but with an appropriate extension, like png.)
