Regarding new code: https://gitlab.com/freepascal.org/fpc/source/-/commit/af3ebf1464224ee159be03d74ab2c73c7f092eef Code has part: ```pascal Function GetNextWord(var l : String) : String; var P : Integer; begin P:=Pos(' ',L); if P=0 then P:=Length(L)+1; Result:=Copy(L,1,P-1); Delete(L,1,P); L:=Trim(L); end; ``` which is allocating, and also it changes the `l` string. It parses line like this: ``` cpu 21222 749 13319 106681 313 0 192 0 0 0 ``` I suggest to rewrite this parsing, w/o allocating strings, without Trim and Delete. Example: When we step on 'digit' char '1' of number '1234', we can read the entire number by loop like this: 1234 = (((1*10)+2)*10+3)*10+4
