synchronization – What is the fastest way to get a bitcoind node to handle 99% of extreme cases?

Currently, when it synchronizes a bitcoind node from scratch, the time needed to go from zero (0) to about 50% is a very fast process, but between 50% and 75% it slows considerably and to 75% – 85%, it creaks almost. stop.

Assuming that the blocks checked during this period are the cause of the slowdown, I wonder if there is a way to clone a node by running and validating a complete node, but at least trusting the blocks up to a number are far enough in the past to handle 99% of incident cases.

I know that disk cloning is possible, but transferring it to a new VPS, for example, does not really try to speed up the process for everyone without sacrificing security.
