Could you please post a little bit more on :<br>
1. What is your platform ?<br>
2. What is your compiler ?<br>
3. What are your compiler option (eg. I hope you do not run bench<br>
without CMAKE_BUILD_TYPE:Release) ?<br>
4. Where is the dataset used ?<br>
5. Where is the source code used ?<br>
<br>
Thanks a bunch !<br>
