Try this link. It just replaces 'www' with 'old'. The day they get rid of old reddit is the day i never hop on that website ever again (though i never use it anyway)
New Reddit is a great way to benchmark your web browser's memory handling or your operating system's responsiveness when you're out of memory. Other than that, it's pretty frustrating.
This is why despite having a more powerful CPU & GPU than ever and 10x more bandwidth than I did 8 years ago websites still seem to load at the same or worse speed as ever.
