My Website is slow.

Website created by Wix ,in India Performance is not well.
I have 1 page with some vector arts no Image.It is taking long time to open.
I used 3 Images (Images was compressed and I upload my Images on another server) then It takes 50 sec to open.

You are better suited contacting Wix Support for this issue.

Also, take note that the speed of your website also depends on the speed of your own internet connection or the speed of the wifi connection that you are using for example.

Plus, it will also depend on the device that you are using to view it on too, an older device will mean that it processes your website slower than a more modern device which will be able to go through your website quicker.

Finally, make sure that you do not have any third party apps installed on your website that could be slowing down your site as it could be these that are slowing down the loading times.

Wix might all be ready to show your website to users, however it might be waiting on a third party app to finish loading itself, so that it can then show the website to your users.

Not always Wix fault.

One last point, when you mention ‘upload my Images on another server’ then do you mean that you are getting your images from another server or that you have uploaded your images to your Wix Media Manager?

If you are accessing your images from another server, then this could be slowing down your site loading times if this connection is slow itself.

Yes " own internet connection " : I want to tell you that if I create a website using Wix it’s performance not will be good in India(Based on India’s Internet).
Yes " too, an older device " I am using modern device.
Yes " third party apps installed " I don’t have Third party app installed.
As a Stranger I am telling you “Wix is slow in India”.I told wix team.But no result(They gave me same answer as like you).
Ex: Make a website using (HTML,CSS,JS) it will be fast.
I know any CMS takes some times to load.But wix is slow in India.
OK,Open another website which has been created by Wix.In India it will take much more time.
Note:Normal website (Using HTML,CSS,JS) will take little bit of time to open on 3G Network,but wix will take much more time.
