Existing benchmark data is not migrated in v10. As such, benchmarks will be empty until you start monitoring with this version and accumulating that data. I don't really care about old benchmarks but there has been some interest in continuing to see it in the benchmarks dialog. Rest assured, the data is still there on your disk and if there is enough interest I can pull it in and merge it with new benchmarks in a future version.
