 * Great plugin, thank you for your work on it.
 * I had a question about cache size. I got an alert saying my cache size is getting
   big:
 * 2587 files, totalling 2351039 Kbytes – that seems huge and I’m not sure what 
   it’s made up of as my website is about 50 pages. Is it saving css and js scripts
   uniquely for each page?
 * I do have CSS in the HTML turned on (which adds to the issue I understand), this
   is a feature I want to keep though as I’m using visual composer that spills out
   loads of css in the source which isn’t pretty. In fact, after finding that issue,
   that’s how I discovered Autoptimize!
 * I’m getting high server wait times so I’m thinking maybe my Autoptimize cache
   is responsible.
 * Thanks, Dan

 * Hi Dan;
    first of all; check the amount of files in /wp-content/cache/autoptimize/
   css and /wp-content/cache/autoptimize/js to confirm if your problem is with amount
   of JS or amount of CSS-files.
 * now the reason for this happening; AO cached each autoptimized file, but as soon
   as one character is different, that file cannot be used and a new one is created.
   that means that if you have inline JS or CSS that changes between requests or
   pages, then indeed you’ll have a huge amount of cache-files and this will hurt
   performance (not due to the amount of files on cache, but because of the fact
   that AO has to re-minimize over and over and because browsers won’t be able to
   use the same autoptimized CSS/JS file).
 * the solution is either to not inline CSS or JS (easy) or to exclude the offending
   code from optimization (requires some peeking and poking around).
 * hope this explains,
    frank

 * Thanks for the lighting fast response!
 * So it’s pretty much all CSS. 2632 CSS files and 16 JS files. All created over
   the last 3 days.
 * I’m not sure which CSS names would be changing with every page, I can’t think
   of any plugins that are changing css file name/path. I’ve just disabled AO to
   check some pages and can’t see anything changing from page to page.
 * I have been making a few changing here and there over the last few days but I’m
   certain I cleared AO.
 * I’ve downloaded some to look at. 90% of them are 939674 kb big with a few 910674
   kb big and about 5 other different sizes. I compared them and found the difference
   to be custom css in the page for different visual composer elements. I also compared
   the ones of identical and the only difference I can find in them is the name 
   of some classes that have been added and the odd line break:

 * If I have 50 pages though, that should just be 50 css files if every page is 
   unique in a worst case scenario?

 * – ignore that, as I can’t of looking at the date created on the files

 * no, as it is entirely possible a plugin (visual composer or other) injects unique
   code that changes with time as well, so it could (as you are experiencing) be
   a lot worse.
 * forgetting the way it looks for a minute, I would in your case absolutely advice
   against aggregating inline CSS. the performance-impact of AO having to create&
   the browser having to load a different CSS-file (even because of minor differences
   such as a selector-name changing) over and over outweighs any performance-impact
   keeping inline CSS in place might have, actually.

 * Understood. I really wish I had picked a theme that doesn’t use VC, for other
   reasons too, it’s more trouble than it’s worth.
 * I will turn off aggregating inline CSS and re-visit after the weekend to check
   the size.
 * Thanks for your help on this.

 * Everything seems to be running smooth and making a normal amount of cached files
   now. It was visual composer making unique inline code for almost every vistor:/
 * I do now have another issue though. AO doesn’t seem to want to work on my Blog
   post pages, it works on all pages and in custom posts fine though.
 * How can I troubleshoot this?
 * I have made a new thread for this to keep your support section tidy.
