I can imagine this.

Quote:
.txts are faster than .mrcs


This is complete BS. txt and mrc are identical. They are the same.

Quote:
.mrc are definitely slower.


Here we go again. Your point has no value whatsoever unless you specify reproducible evidence of it. Until then it's just another round of "This is what I think so that is how it is" BS we went through a while back about yoiur consistent whining about goto loops on your system. An utter waste of time. Please produce the code which can prove your claim or stop talking about it.
