<strong>Memory</strong>
</p>
<p>
<strong>Private:</strong>
Resident memory size that is not shared with any other process.
This is the best indicator of browser memory resource usage.
</p>
<p>
<strong>Proportional:</strong>
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.
