Dear All,
we run K12-Fedora10 in a production environment. Yet, I suppose that
some of you have probably used (or are going to use) the NetBeans IDE in
educational sites. Thus, I wonder if you can help us understand this issue.
NetBeans IDE is terribly slow. Menus appear seconds after the mouse
asked for them. Window background refresh happens at such a slow pace
that you can relax and watch the progress. Strangely enough, Eclipse IDE
runs at normal speed. We noticed also that if the *same* client, instead
of starting in PXE mode, boots from a local HD and then uses VNC to
connect to the server, NetBeans IDE runs at almost normal speed. What
kind of viewer does K12 use and why VNC viewer appears much faster in
this case?
An explanation can be that K12 downloads a default O.S. onto the
client, while a local VNC viewer, although running on top of a similar
Fedora 10, makes optimized use of the client's graphic card with
specialized drivers. Nonetheless, I wonder if a drop-down menu or a
window refresh is such a graphic intensive application...
