Looking at the profile consisting of a single sample is very confusing. See the screenshot.

Alternatively idea:
Use dynamic sampling interval. Start with e.g. interval of 100 bytes and increase it as number of samples grow.

This way the precision of the profile could always be kept on a certain level.
