On search engines, I've seen most tech guys say for optimizing websites via cPanel, one should use the Option 3: Compress MIME Types, not the Option 2: Compress All, because "...compressing all website content can make webpage images show irregularly..."
Is the Option 3 really good or better?
After selecting and using the Option 3: Compress MIME Types, I've found very often there are some images that load very slowly and finally can not show up on some of my webpages that have more than 10 images.
Previously, I used the Option 2: Compress All including images, js and all others---I saw almost all images were loading normally/faster and all images were able to show up on my webpages finally.
What do you think?
Do I need to re-use the Option 2: Compress All. Any big potential disadvantage for using the "Compress All" option?
Other questions: I have already enabled Zlib compression via root to Apache files, can I enable the cPanel Optimize Website features that are based on Gzip compression, at the same time? Any conflicts between Zlib and Gzip?
The two compression methods have their own disadvantages in several situations. If using only one of the two compression methods, generally speaking, which compression is better, Zlib or Gzip? (I have tested using the two compression methods together, and I've found there are almost no differences as for the website performances, compared with using only either Zlib compression or Gzip compression. Maybe there are some differences but I've not found yet)
Thank you very much for any advice/tip!
