Network file save takes too long #22

Closed m00natic closed 10 years ago

m00natic commented 10 years ago

The way TRAMP works when appending to file is first copy the whole file, then invoke local write-region. So each time VLF adjusts a chunk, the whole file is copied through the network. So either:

  1. VLF and TRAMP work together and reuse the initial temporary whole copy for all batch writes.
  2. VLF itself makes a whole copy, saves multiple batches and then copies back through the network.

In any case, the way VLF appends to file, seems useless when it's done through TRAMP.
