One vexing thing for me about it was during routine day to day operation a portmaster upgrade sometimes inexplicably would tickle something that allowed the thumbnailing to speed up again but only temporarily. In writer (perhaps others) from File->Printer Settings->Properties->device, the printer language type, if you have a .pdf selection you may want to try enabling it. Or if your spadmin works (mine's complaining about read only directories this morning) try selecting a driver for your printer not for postscript or anything other than pdf. Converting the ps to pdf and back again eats a lot of cycles. I don't remember specifically and can't test it due to the r/o issue now but the cups driver selection was not the essential bit so much as getting LO to generate .pdf for the printer.
