Measuring memory usage in a multi-process browser

## Summary

| Memory Memory Private: Resident memory size that is not shared with any other process. This is the best indicator of browser memory resource usage. Proportional: Accounts for each page of memory as a fraction based on the number of processes that have it mapped. Thus, for each page of memory mapped by two processes, this sum will count half of the bytes towards each. Therefore, this number is greater than the private count. (Note that the memory for this tab is not included in the browser totals)

Browser | Private | Proportional
| k | k

Note: This page will show memory use for all running browsers, not just Chrome.
Note: Chrome includes memory used by plug-ins, other browsers may not.
