PCTRACE-CACHE

Syntax

PCTRACE-CACHE [on|off]

Variable

VT_PCTRACE_CACHE

Default

on

Description

When the reliable stack unwinding through libunwind is used, caching the previous stack back trace can reduce the number of times libunwind has to be called later on. When unwinding only a few levels this caching can negatively affect performance, therefore it can be turned off with this option.
