openvidu / openvidu.io Goto Github PK

Hi there!

Since we are using OpenVidu in our product, it's common to access openvidu.io on a daily basis to reach the documentation and check new releases. One thing that bothers me the most is to see the carousel images half loading every day. Then the carousel changes to the next image, which is still half loaded. After a full carousel shift, the images may be full loaded.

This issue happen for 3 reasons:

• I'm on a slow network (nothing we can do, so ignore that)
• The image's max-age cache are too short: 600
• The image's size are way bigger than the carousel and the filesize is not optimized.

Regarding max-age, 600 means 10 minutes, which is very unusual for home page images. Would be possible to increase that to months and use cache busting technique (filename hashing for example)?

Regarding the image itself, the first image is this one. It has a size of 1920x1080 px and almost a filesize of 3mb. There's a lot room for improvement here, like lowering the resolution to be near to the carousel max size, and using JPEG compression to reduce filesize.

I think this may have some SEO impact as well, since loading speed may be used to rank OpenVidu's home page.
