To explain the exact problem: You can't insert data into the middle of a file, just overwrite it from that point forwards. So you can't edit without completely overwriting everything after that point, unless your data is made of fixed-size records.

So NFS is almost bound to be slow. Could you make the update on the server that is sharing the NFS to you? That should be a fair bit quicker.

Can you share the other resources (and competing load) on the server?
