The VTune™ Amplifier XE seems sluggish

If you find the VTune™ Amplifier XE for Linux* to be slow to respond when collecting data or displaying data, here is what you should know to get the best responsiveness.

  1. Make sure your project directory (and consequently, the result files) are located on a local disk and not an NFS-mounted directory. This will significantly impact performance of the tool in several areas: writing of the results will be slower, updating project information will be slower, and when loading the results for display you may see delays of several minutes.  By default, the projects are stored in $HOME/intel/amplxe/projects.  If your home directory is on an NFS-mounted drive to facilitate access from multiple systems, you should ensure that you set the project directory to a local directory at project creation.
  2. Application binaries should be on a local drive and not an NFS-mounted drive. Symbol information is parsed during results analysis and if the binaries are on an NFS-mounted drive, Amplifier XE will take longer to present the results.

Note: there is a known performance issue with Updates 3 & 4 when filtering results via the thread timeline, e.g., removing unwanted threads.  This has been resolved with the release of Update 5, available on the Intel Software Products Registration Center since Sept. 6, 2011.
