One of the things I find myself stuck on constantly is determining to what level performance actually matters. For example, ruby vs go. Yes, I understand a faster runtime/framework is probably a good thing. But there are millions of sites, just like this one powered by something like ruby, which is clearly miles slower than go. Yet seems to not only be surviving but thriving.
For the higher level development and projects (where 99% of the projects are), the performance (difference) is not relevant. Your customers will not see the diference between a Wordpress and a C++ monolith.
But if you want to build a load balancer, a SQL database, a Graph database, to cut down the servers from 2000 to 200, or build a real time back-end service you will notice the difference.
