It's actually a performance enhancement by "not" having to do this.Yes, but the conversion is not very heavy, the entire statement translates to perhaps 8 assembler instructions, not more than 50 CPU clock ticks.And this is the filesystem, so it can be called many times. Thus, any saving is a performance boost regardless how small.
I tend to disagree, I bet the gain wouldn't be even measurable. Pozdrawiam KMK
