Hi,
We have Red Hat Enterprise Linux Server release 7.8 (Maipo), which by default has vim 7.4 installed. I am trying to compile the latest vim 8.2 (official release, without later patches). I went the usual way: download the sources, configure (default settings, only --prefix redefined), make, make install ... And got the following build:

The problem with this build is that the GUI version is very slow. For example, it takes about 6 sec to start. Below are some unnecessary large timings from the startup profiling:
==================================================
161.380 159.404: expanding arguments
...
1344.137 1143.949 1143.949: sourcing .../share/vim/vim82/ftplugin/man.vim
...

==================================================
Once started, gvim more or less works, until I decide to use the terminal functionality. This is where the things become really indecent. Forget using the terminal interactively, a simple ":term ls -l" takes several minutes to run. Gvim is unresponsive during this time. Once the terminal window becomes finished, gvim becomes responsive again, but will periodically hang if you decide to navigate in the finished terminal window. During gvim hanging, the call stack looks like this:

==================================================
Which makes me thing that the problem is GUI/X server related. And true, this does not happen in the console verion of vim. FYI, My X server is one of the latest versions of vcxsrv running on Win 10.
I believe that the version of vim 7.4 that comes preinstalled is faster. Unfortunately, vim 7.4 does not have the terminal functionality to compare the same things, but its start-up times are much faster, without the lags above (same vimrc is used). The vim 7.4 is built with -DFEAT_GUI_GTK and various gtk header folders included. I don't have those headers on my server, that's why GTK GUI is not used by configure...
Any advice would be appreciated.
