OS X + NFS on VPS - does anyone use it?

Question

macOS

I have a macbook with a 128GB SSD, there is not enough space, but I can’t fork out for a 512GB drive. The task was to expand the place at the expense of an external source.
Requirements:
- work with the FS as with a local folder, crutches like fuse for FTP are not suitable, I personally have a negative experience with periodic freezes and a long delay with operations in the FS.
- permanent access and empty ports (external drives / flash drives are not suitable).
In a word, this is the task. On the computer, you need a folder that will work as a local folder, but will not take up disk space.
There was an idea to buy a VPS and set up NFS or AFP on it in order to mount a folder to the system. I would like to know if anyone had real experience with a similar bunch. How big are the brakes when pinging 60-70ms to VPS? What are the pitfalls? What will happen with a large number of read-write operations (when it becomes necessary to move several thousand files of 50-100Kb each)?
UPD: what network FS would be the best choice for this task?
UDP2: I tried Yandex.Disk via WebDav, the download speed of a large archive is high, but if we upload a lot of small files, it’s sooooo slow - it’s not good.
UPD3: OwnCloud + WebDav doesn't work either. Even with nginx OwnCloud dies on a large number of files, I also tried Swift storage, the speed dropped by half.
UPD4: I tried to raise NFS on a dedicated server. Again, the speed when working with small files is low. Then I tried in Russia + fine-tuning NFS like enabling the async option. As a result, it is still inconvenient to work, such a bunch is not good. It became clear that for fast work with a remote file system, you need a local cache (a similar scheme is used in S3QL).
UPD5: Started netatalk and NFS on my HTPC purely for the sake of testing. The speed is good, it also processes a lot of read / write operations normally, and in general the option is a good option, only after leaving the house you lose access to data. As a result, the only option is to increase the storage directly in the laptop.
UPD6: Which SSD to choose for MacBook Pro 13 (Mid 2014)? - continuation of a story

Answer 1

any network fs in these conditions will be a pain.
in order of priority:
- upgrade native ssd (expensive)
- jetdrive lite (ok)
- external drive (cheap)
