Processing taking long and making feeds blank

hi. I’m experiencing extrememly long processing times (almost looks like the process is stuck). I only have 200 products and the main issue is that while a feed is taking all this time to process, it becomes blank which obviously then affects the setup in merchant centres (Google & Bing). Is it not possible for 1) to speed up the processing time or at least 2) For the feed to remain intact untill processing is complete?
Thanks
