I noticed my VIM write/save file for a network path is quite slow.

I found out VIM saves files with approximated speed of 20mbps (2.5MB/s). Network is 1Gb/s local area network so I believe the bandwidth is not a problem. Notepad text editor or Notepad++ saves the same file 10 times faster. It does not make difference if I have access via windows share and UNC path (\\server_name) or map it as local drive.

I made all tests with a clean VIM (gvim.exe -u NONE) so I believe this not a plugin issue.

What else can I check to speed up file saving?

    Does the situation improve if you disable swap files with :set noswapfile? If so, you might consider either disabling them unconditionally or setting the 'directory' option to ensure swap files are on local drives and not on a network share... – filbranden♦ Jul 9 '20 at 19:57
  • Using no swap change nothing, the speed is still low at saving file. – gradzikb Jul 10 '20 at 4:42
  • How are you editing over the network? Over a graphical ssh connection or using the builtin netrw? – D. Ben Knoble♦ Jul 10 '20 at 12:11
  • The file is open with gvim by Windows 10 file manager via UNC path or mapped network drive. – gradzikb Jul 10 '20 at 13:34

I've solved my problem compiling VIM with bigger write buffer size (\src\structs.h).

Default value

#define WRITEBUFSIZE    8192    // size of normal write buffer

My new value

#define WRITEBUFSIZE    8192*1024   // size of normal write buffer

VIM write speed to network drive is similar to Notepad++ now, it's around 300 Mbps in my case.
