 * We have just fixed the issue. File system on a server choked up with all the 
   small-size files.

 * Do you have any advice on a faster way to render the files? We migrated a site
   and it takes quite a while to rebuild some of these pages as there are multiple
   formulas.
 * In the ql-cache folder, there are numberous .txt files, but it seems like there
   are only a handful of matching .png files?
 * Thanks,
    Also, best method to donate?

 * WP-QuickLaTeX caches images locally on your server. So that, as soon as all images
   are generated (when first visitor opens the page, or pre-cached) – images will
   not be re-built in future.
 * Then page loading speed will depends on your webserver and its optimizations –
   how fast it serves the static content (svg, png, etc.).
 * To boost up page loading speed further, use cache plugins, like WP-SuperCache,
   Autoptimize and fast web-server like nginx.
 * P.S.
    Donation links are on the right in the WP-QuickLaTeX admin page.

 * For sure, I understand the caching and all – it’s just that on “first page load”
   it takes forever to initially generate. Until the generating is done, our page
   actually crashes. (it’s still generating since my post as I can see the ls-cache
   still building).
 * Do we just have too many formulas on each page?

 * Indeed, sounds like page has a lot of formulas.
    If you have access to previous
   hosting – you can just copy the ql-cache.
