Riverbed wan appliances were always great for this. I would have loved |

to see an open source version of their hash-zip-send as it worked |
| 9 |
amazingly well. |

however, from [1] you can mount.cifs with option fsc, and perhaps (sorry |
| 11 |
not tried myself) then use something like cachefs to make for a |
| 12 |
controlled size and location for that cache? also [2] might be of |
| 13 |
interest to you |

fsc Enable local disk caching using FS-Cache (off by default). This |
| 17 |
option could be useful to improve performance on a slow link, |
| 18 |
heavily loaded server and/or network where reading from the |
| 19 |
disk is faster than reading from the server (over the network). |
| 20 |
This could also impact scalability positively as the |
| 21 |
number of calls to the server are reduced. However, local |
| 22 |
caching is not suitable for all workloads for e.g. read-once |
| 23 |
type workloads. So, you need to consider carefully your |
| 24 |
workload/scenario before using this option. Currently, local |
| 25 |
disk caching is functional for CIFS files opened as read-only. |
