Memory Before-and-After Comparison Worksheet
Enter comparable memory readings and task times that you measured yourself. This worksheet calculates the differences; it cannot determine causation, verify that cleanup occurred, or certify that a computer is faster.
Use comparable observations
Keep the applications, files and background workload the same. Record whether the task is a first run or a repeated run. MiB is the unit expected for memory; convert other units consistently. Run several comparisons and retain the raw observations.
Formulas
RAM change = before − after. Time saved = baseline − after. Time saved (%) = (baseline − after) ÷ baseline × 100. Positive time saved means a shorter recorded task time.
Questions and answers
Does this page read my RAM automatically?
No. You enter the observations manually. The page only performs arithmetic in your browser.
Are the numbers sent anywhere?
The worksheet code sends no data. Its CSV export is generated locally. Ordinary hosting access logs and any separate download-service activity are not worksheet measurements.
What does a negative time-saved result mean?
The entered after-cleaning task time is longer than the baseline. Repeat the same task under comparable conditions before drawing a conclusion.
