How should I organize WordPress with GitHub without growing burden period of my site?

I need to join My site: Juicers Blenders with GitHub yet the issue is at whatever point I work with my site the heap time my site increases several clients cry about load time,

Is there any reaction for join my site without developing weight time?

Much appreciation to You.

I couldn’t open the link, the site seems to hang forever.

I’m not sure what you’re asking here, you mentioned it’s a WordPress website, which is an unsupported platform on GitHub (which only supports GitHub Pages websites for repositories or user accounts).

What would you expect to achieve by “joining” your site to GitHub?
