Subject: Re: [Engine-devel] GWT Dev Mode unbearably slow in WebAdmin
I'm afraid I need to resurrect this. I'm again seeing unbearable slowness
with GWT Dev Mode in webadmin on master. The first load is tolerable, and
one or two refreshes are ok, but after that it bogs down and is unusable.
Some suggestions (that have been already mentioned in this thread a while ago):
1, use gwt-maven-plugin 2.5.1 instead of 2.4.0
in root pom.xml change
<gwt-maven-plugin.workingRefresh.version>2.4.0</gwt-maven-plugin.workingRefresh.version>
to
<gwt-maven-plugin.workingRefresh.version>${gwt.version}</gwt-maven-plugin.workingRefresh.version>
2, disable GWT persistent unit cache
in frontend/webadmin/modules/pom.xml find
<artifactId>gwt-maven-plugin</artifactId>
add <persistentunitcache>false</persistentunitcache> to
<configuration>
-or-
make gwt-debug [usual options]
DEV_EXTRA_BUILD_FLAGS="-Dgwt.persistentunitcache=false"
3, try out GWT Super Dev Mode
Vojtech
Anyone else?
