ROOT Does Not Invest in & Prioritise I/O performance and data formats
The ROOT team may not give enough priority to ensuring ROOT data structures and I/O performance are adequate for the evolving computing models of data delivery via streaming, caching etc.
I/O performance coould become a significant bottleneck in data performance, streaming, access - and starve CPU resources; this is also key for content delivery models required to address storage costs and concerns in the near future. This is an areas where all experiments will benefit from effort invested in the underlying I/O system.
Start R&D program on I/O and data management in ROOT, prioritse above other functions; has major cost impact for the long term.
This is an area where improvements will benefit all experiments.
