Hello!
I recently switched from Windows 7 to Ubuntu for GWT development, and
I am seriously considering moving back, as GWT debugging under Linux
("Debug as Web Application" in Eclipse) is painful - much slower than
under Windows.
My test: same project/code (GWT front-end, GAE back-end). While on the
project page (fully loaded), I hit browser's "refresh" button, type
login credentials into the login dialog (part of my GWT app) and then
wait until I see my page with some data from GAE (also in the
debugger, in the same Eclipse workspace, different project). Measure
time. Then I hit "refresh" and login and wait until I see full page
with data. Measure time. And again. And again.
In Linux, it consistently takes about 21-28 seconds from "refresh" to
destination page. Sometimes "refresh" never finishes, so I have to
close the tab and open a new one. Even typing credentials is slow, as
there is a noticeable delay (~1sec) between a key press and a symbol
appearing in the text box (only under the debugger/plugin; "compiled"
javascript is relatively fast).
In Windows, it consistently takes 6-8 seconds (mostly typing) from
hitting refresh to the "after login" page. If I exclude 3-4 secs it
takes me to type credentials, linux will be ~8x times slower than
Windows.
What can I do to speed up GWT's debugger/plugin performance in Linux?
My set-up:
Linux: 64bit Ubuntu, desktop edition with "linux-server" kernel; the
latest sun java x64 jdk/jre; Eclipse 3.6, GWT 2.1, AppEngine 1.8. GWT
plugin for Google Chrome (Firefox plugin fails to install, probably
because of x64 environment).
Windows: 64bit Win 7; latest Java, same eclipse/gwt/appengine. GWT
plugin for Firefox.
Same computer (Intel i3 quad core, 7200 rpm hdd, 4GB RAM) - dualboot,
no VMs.
What's wrong with my set-up? Is there anything I can do to improve GWT
debugging performance under Linux?
Regards,
MG
