What is the quickest way to bring a bitcoind node up handling 99% of edge cases?

What is the quickest way to bring a bitcoind node up handling 99% of edge cases?

Currently when syncing a bitcoind node from scratch the time of going from zero (0) to about 50% is a very fast process but somewhere between 50%-75% it slows down considerably and at 75%-85% it grinds to an almost halt.

Assuming that the blocks that are being verified during that time are what is causing the slowdown I'm wondering if there is a way to basically clone a node by still running and validating a full node but at least trusting the blocks up until some number that is far enough in the past to handle 99% of edge cases.

I know that cloning the disk is possible but transferring that to a new VPS for instance is not so looking for ways to speed up the process for everyone without sacrificing security.

Known Optimizations

Setting the dbcache to a higher value (currently using 2000 on a 4gb RAM machine which is 25% of the available RAM)
