Normally you should not do anything about handling of short-lived data, because the default settings are good enough for almost all situations. Sometimes you may hit a situation where the settings are not good ("pathological case"). However, it would normally require a deep understanding of the storage system to deal with such a situation, and we will in general consider this as a bug and try to fix it. Therefore if you find such situation you should report it to Lisp Support, following the guidelines at
www.lispworks.com/support/bug-report.html
.
Problems with short-lived data normally just reduce the performance of some part of your application. Normally the best solution is to optimize the code to do less work, including allocating less.
To do that, first find the bottlenecks in your application by using profile (and start-profiling and stop-profiling). time and extended-time can then be used to determine how long specific operations take, how much they allocate and, for long operations, how long they spend in garbage collection. Based on this information you can then decide what to try to optimize.
