.vue compared final renders (jpg i assume). Look at the file sizes to understand the differences in speed. I think it is as simple as that. Saving over a network. This phenomen i know since the early days of networking. I guess it has to do with memory allocation. What the operating system probably has to do is, to save the file temporarily on your local disk and then start the network copy functions (with less memory maybe even because the major application allocates a lot of memory already). Instead of having it on your local disk already and do it directly when you do it as a system function. What i learned as well is that saving over a network can be a dangerous thing. Another source for potential coruption of files i would say. What happens when the network connection breaks down in the middle of the saving mode? What happens when the other computer crashes by any reason? A lot of extra danger i would say. Especially when you have different file systems even (I have a network of Macs and Windows PCs). So i stay with the classical way. Save it locally and transfer it then manually to another computer.
