What if my instrumented application is too slow or uses too much memory?

A lot of effort has been expended making PurifyPlus execute quickly and with as small of a memory footprint as possible. As with any complex software program however, there are going to be times when the program being analyzed and PurifyPlus combine to use a large portion of the available system resources. This can result in lowered performance or high memory usage. PurifyPlus has been designed with this fact in mind and it offers several different ways to modify the behavior of PurifyPlus to run faster or use less memory and still help you gather data. The right approach will vary based on the situation, so you may need to consult different resources to find the right approach for your specific situation.

The first step should be to read the Tips section of this online help to see if there’s something helpful there.
