I have extremely large .txt file (around 180 MB in the MathML form). This .txt file contains simplified expression in polynomial form and can not be reduced more. After starting the import process, after two days Mathematica 11 is still working. Is there any solution how to speed up it. Ram memory is 10% used all the time.
Large file is uploading long time (few days and nothing) MathML .txt:
Small .txt with the same MathML structure is uploading fast (few swconds):
SetDirectory[NotebookDirectory]; imp = Import["num.txt"]; eq = ImportString[imp, "Expression"];
