Hi, Let's say, I have some .tex which will generate more than 100 pages in PDF. The pdflatex consume a bit longer to finish in one core. Here I have physical 4 cores with virtual 4. I wonder whether or how can make it fast. In my situation, if I corrected a minor place, I needed run three times pdflatex and waited more than 1 min to its finish. Thanks ahead for your suggestions, Best regards,
