lightroom very slow. Upto 5 hours to load roughly 700 Raw files

Its sad to say that after roughly 20 years of using Adobe products i find myself searching for an alternative. I was used to buying a single user licence which turned into an annual licence and now an monthly licence for a cloud based software, As a wedding photograhper i find lightroom very slow. Upto 5 hours to load roughly 700 Raw files. Editing is just as painful. 

There is no solution to this issue, unless i spend thousands on a new pc which isnt needed to run other and sadly cheaper software. Its been a blast the last 20 odd years Adobe but i must say good bye. The apps you have built have very quickly made very modern systems seem old and very incompatible with your software. 

iv spent around $6800 on licneces to your products ober the last 20 years as a wedding photographer and sadly i cannot justify the outlay on a system thats compatible to edit that doesnt crash halfway through due to high Ram usauge.
