compressible?

Hi, I was noticing that the (binary) cpu_0 file that lttng generates seems to be pretty compressible. For example, using gzip, I compressed three cpu_0 files: 25M -> 4.2M 57M -> 8.3M 56M -> 8.2M Do you think including a compression step would be useful for minimizing disk traffic due to the instrumentation? The potential benefit is seems to be a factor of five reduction in disk traffic, but I don't know how big the costs are. It's also possible my traces are particularly compressible because of patterns in what I'm doing. Johnicholas
