14.8 Making Data Access Faster
Tips that may help for either classic or netCDF-4 formats
For all netCDF formats:
- If data must be written in a different order than it is read,
consider rewriting the data to the most efficient read order.
- If writing is a bottleneck and you write all data values for each variable,
consider turning off default "fill mode", which
pre-fills data with
- Advantage: saves write time.
- Disadvantage: eliminates
possibility of detecting unwritten values.
- When writing from multiple processors, use parallel I/O.
