When I add new product > it adds correctly BUT :
* After save it loads for minutes then eventually times out
* For the next ~5 minutes the server becomes overloaded and everything is 503 / or very slow.
* Does my server require an upgrade or is it just mis-configured ?
Current Server spec :
I mean error 504 , or it says :
"Service temorarily unavailable"
Note : This only happens when adding 1st product.
After this , I can add more products without any problem.
But if I try again a few hours later , 1st product causes overload again.
You need to check server load while you are performing such task like adding product into cart or working on checkout if server capacity is full then i think you need to use load balancer for this.
another way is to check if you have alot customisation in add to cart functionality then you need to minimise the code minimise means you need to optimise the code.
Lastly this issue can be due to 3rd party extension you need to check those as well the batter way to check this is to disable 3rd party one by one and on local environment and then check.
Hope this helps you.

@audiobuy_llc Can you please provide the public url so that we can have a look on this?
@audiobuy_llc Have you done any customisation in that?
It seems your indexing is not done properly and it gets stopped in between.
Previously we have faced the same issue but that was due to some customisation which save every child product on saving a parent product.
So please check if there is some customisation done there.
