I'm currently trying to understand some very very strange behavior in one of my C programs. Apparently, adding or removing a seemingly inconsequential ...

When I tried to use wincachegrind and get the cachegrind file, it returns Cannot find call target. cachegrind.out line number:68 Anybody kno ...

Inspired by SQLite, I'm looking at using valgrind's "cachegrind" tool to do reproducible performance benchmarking. The numbers it outputs are much mor ...

I want to use cachegrind to do some performance profiling on the OpenJDK JVM. (BTW, if this is Not A Good Idea, I would like to understand why.) The ...

It is well known that, the callgrind analysis tool of the valgrind suit, provides the possibility to start and stop the colection of data via command ...

I am studying about cache effect using a simple micro-benchmark. I think that if N is bigger than cache size, then cache have a miss operation every ...

Recently Herb Sutter gave a great talk on "Modern C++: What You Need to Know". The main theme of this talk was efficiency and how data locality and ac ...

I am trying to create a valgrind (cachegrind) analysis of MySQL client connections. I am running valgrind with --trace-children=yes. What I want to ...
