process.hrtime() is much slower in 14.x

[spazmodius]

process.hrtime() takes twice as long to execute in Node.js 14, compared to Node.js 12.

• Version: 14.15.0 vs 12.18.4
• Platform: Microsoft Windows NT 10.0.19041.0 x64
• Subsystem: process

What steps will reproduce the bug?

Running benchmark/process/bench-hrtime.js in Node.js 12 and 14

hrtime should be about 2x faster in v15

You mean fixed in 15? Because what you posted above still shows degradation in 14.15.1
