Hi,
Working with JCH optimize a few years now, it works great.. it requires a lot of testing when optimizing. With most extensions/plugins there shouldn't be to much problems. With more "advanced" extensions you can run into some trouble and have to figure out how to exclude them. I have some sites that score AA grade with a loading time of around 4 seconds and some "B grade" sites that loads within 2 or 3 seconds. It is an important tool you need to optimize so you see that is some improvement while optimizing. Although some websites that have a horrible score according GTMetrix (lets's say 10-20 seconds) are loading within just a few seconds when you visit them. Funny.. Am I being crazy or just a fool who takes optimizing to serious ?
What most of us run into; some clients have picked there own hosting; cheap crap hosting, so a part of the optimizing is lost. I see it often when finishing a website on Siteground (working domain) and then transfer it to their host; Aaaarrggh..
.
Never scored 100-100. Mostly because of the fonts that have to load and some small png files in the templates.
My scores in the attachments, not using a CDN and stopped to optimize any further because I was satisfied and it runs stable.
About Admin tools; happy with it.. protecting all my websites with it for over 2 years now.
One thing; turn of the notification mail. Only a mail of successful logins is enough. Otherwise you go crazy
What need now is a way show video for header and keep good performance. Problem is when linked Vimeo and Youtube don't support custom dimensions. ( full width* 1929x600 ). tried a few extensions but they all load weird when on top of the webpage. Now made a custom loop of 1920x700 of 15mb. This increases the page size badly. But they want it this way...
