what does "within 10% of the performance of the C++" mean?

[publicocean0]

sorry what does "within 10% of the performance of the C++" mean? 10% less than c++? -> c++ 100 ops , java 90ops 10% in absolute -> c++ 100ops , java 10 ops

comparing other similar project in java the performance is comparable with c++ .... are you sure ?
