Hi there. So far I think this problem is isolated to a variable product with 99 variations – https://asphair.com/product/new-infiniti-regular-shades/
The more shades are added to the cart, the slower the loading time becomes until it jams up completely and customers are presented with a 504 Gateway Timeout.
The data below shows cart page load speed against no. of shades(tubes) added:
1 tube – 1.64sec
7 tubes – 3.07sec
11 tubes – 6.52sec
14 tubes – 20.7sec
19 tubes – 41.37sec … you get the idea.
When I switch to Storefront theme I can add as many shades (100+) to the cart as I like with NO effect on site performance. So this issue must be theme related?
I have tried disabling dynamic caching as recommended by my hosting provider – no joy.
Thanks in advance.
