 * I have updated to version 2.9.0.1, and Parallel Optimizations eats up server 
   resources. I think this option should be off by default. I think a lot of people
   may come undone with this option switched on by default. I have a VPS with 4 
   core CPU and 4GB ram.
 * If I want to update this plugin on all my clients sites I will need to go into
   settings and turn it off or else to server crashes on multiple image uploads.
 * Thanks

 * If you’re having problems, it is most likely that there is something else going
   on besides just parallel opt. I ran it on a 1 core VPS last night with 10 resizes,
   and retina turned on. Uploaded 20 images, and had no problems whatsoever.
 * [@steveokk](https://wordpress.org/support/users/steveokk/), yes, that is the 
   url for parallel opt.
 * Are either of you using the WP Retina 2x plugin?
