## set cachesf

`set cachesf num`

Use this command to change the scale factor for setting the default cache size (in bytes), which is calculated according to this formula:
X grid size * Ygrid size * 8 * cachesf

The default cache scale factor is 1.

### Usage Notes

This command is available with GrADS version 2.0.a8 or later.

The cache size is only relevant when reading HDF5 and NetCDF4 data types.

Cache size is set on a per-file basis; the cache size will be different for each file opened in GrADS. After a file is opened, a new cache is allocated for each variable that gets displayed in the file. Be careful

Current value of the cache size may be discovered with the `query cache` command.

Please see the documentation on compression for more details.
