When TotalView encounters a reference to a shared library, it normally reads all of that library’s symbols. In some cases, you might need to explicitly read in this library’s information before TotalView automatically reads it.

On the other hand, you may not want TotalView to read and process a library’s loader and debugging symbols. In most cases, reading these symbols occurs quickly. However, if your program uses large libraries, you can increase performance by telling TotalView not to read these symbols.
