Is there any way to improve sshfs speed on amazon aws?

Question

My ping to the AWS instance is on the level of 50ms and cat'ing files through the ssh takes way less than second, but when I mount directory using sshfs and open it using SublimeText3/Gedit lags are greater than 10 seconds. 1. Is there anything I could do to reduce those lags? 2. Why it works like that? 3. Are some better tools for remote file editing?

My ssh config:

Host myinstance
  HostName ********
  User ec2-user
  IdentityFile ~/idfile
  Compression no
  Ciphers arcfour
  ServerAliveInterval 15

As a first step, I'd suggest adding this line to your settings (Preferences -> Settings-User):

"atomic_save": false

and see if that does the trick. My answer to this question has some more details behind why this works, but basically what Sublime is doing with atomic_save enabled is creating new temp files and deleting the original file, then renaming the temp back to the original's name. This leads to a very significant increase in traffic over the connection, and if the server on the other side of the pipe is a little bit laggy anyway, it can really slow down Sublime.
