Yup. There is a huge speed difference between the kernel going to the disk/SSD
to read from a file, vs. the kernel

Caching affects sys. Might
I have several queries which I time with ‘.timer on’. I repeat the queries
350 times. I see a big difference between the minimum and maximum time
needed to run the queries. Especially for sys. Like:
Number of iterations 350
Timing OR version
real: 120.86, min: 0.2710, max: 0.5540, max/min: 2.04
4 matches
