Hi,
I am have a store on contact lenses in which I managed the inventory of each prescription combination but now since there are configurable products having more than 2000 simple products but now even a single attribute or image cannot be changed since it keeps on loading and then timeout.
This is a serious issue with magento2 since I have suggested the client to move to magento 2 and now a major bug in magento2.
Any suggestions.

Did u checked magento error log or appache error log ?
As there are so many simple products in your configurable product, you have to increase the PHP variable values.
Try out following values
memory_limit = 1G max_execution_time = 180000 max_input_vars = 1000000
The max_input_vars variable plays an important role here.
If you are submitting very large data, the max_input_vars value should be high.
