From https://openresty.com/en/xray/: High CPU Usage Up to 90% reduction in CPU usage

Large Memory Consumption Up to 90% memory footprint reduction, less than 5 minutes to locate memory leaks

Slow Disk I/O Capable of 80% reduction in disk I/O saturation and latency

High Network Latency As much as 90% reduction in response latency and timeout errors

Smells snake oil to me

The percentages of improvement that result from finding and tuning the worst paths in a system are often this good unless it has already been done once for the system.. Sun engineers put a lot of thought into algorithms and where bottlenecks should be but still had some improvements like this when first applying DTrace.
