Spin wait C++11

I have the following struct

struct info {
 unsigned long a;
 unsigned long b;
};

atomic <info> data;

used by a writer thread and a reader thread. The reader has to respond to the new values as fast as possible. To do that I’ve implemented the following in the reader :

while (true) {
  auto value = data.load();
  // do some operations given these new values
}

This operation is very processor intensive. I’ve opted for this method because I believe it’s faster than, for example, using a condition variable and then waiting for the reader thread to be awakened when data changes. Also, the data updates quite frequently, hundreds of times per second. Is there a better way to do this while still having the fastest reaction time?
