+++ This bug was initially created as a clone of Bug #1149865 +++ "/usr/bin/gstack is a script which invokes gdb and it's slow. Especially for threaded C++ apps." Background: Most of the time is spent reading the symbols and unwinding the stack for each thread. GDB maintains 3 different symbol tables which causes the slowness. There is a discussion about speed/performance from sourceware.org: https://sourceware.org/gdb/wiki/SymbolHandling?highlight=%28faster%29 --- Additional comment from Jan Kratochvil on 2014-07-15 11:24:03 EDT --- Upstream PR http://sourceware.org/bugzilla/show_bug.cgi?id=16405 --- Additional comment from Jan Kratochvil on 2014-10-01 15:50:28 EDT --- [patch] Fix 100x slowdown regression on DWZ files https://sourceware.org/ml/gdb-patches/2014-10/msg00020.html
