This chapter introduces a strategy for measuring the potential performance gain that could be yielded from an increase in page size. We begin by discussing a powerful Solaris tool,
trapstat, for easily quantifying the potential gains of using a larger page size. We discuss “
trapstat(1M).” on page 640. We then follow by discussing legacy methods to estimate the gain in Solaris 8 by use of the
To determine whether we can improve application performance by using a larger page size, we need to determine the amount of time the microprocessor or operation spends servicing translation lookaside buffer (TLB) misses on behalf of a target application. ...
