Re: GWT project runs slow in Hosted mode

Hi Dorothy, Most of the cases reported on this thread involved using multiple GWT libraries along with GWT core itself. As Jason suggested above, it's possible that one of the reasons for the slowdown is many Java to JS boundary crossings in the associated libraries. I'm not familiar with GWTX, bu

We are having the same issue upgrading from 1.5 to 1.7. For our application, we have GWTX in addition to the GWT. For our project, we have 4 GWT modules that are in development. For hosted browser with the -noserver option, our launch time in 1.5 was ~90 seconds and is now over 10 minutes in GW

We have same issue and still can't resolve it. On relatively large application (overall about 20 tables and forms) with GWT 1.6 and GWT-EXT 2.0.6 hosted mode performance is really not adequate. Refresh of the page in hosted browser takes more than 30 seconds. Same application is quite responsive

I migrated a project from GWT 1.5 to 1.6 with extreme slowness in hosted mode - compiling and running in web mode performed the same with no performance hits. I was using the GXT and gwt-google-maps modules. I went from 5 second to over 60 seconds to do a simple refresh in hosted mode. It has no

Hi, I cannot imagine that this is a hardware issue! Since I switched to GWT 1.6.4 I had the same expierience with a 2GHz Core2Duo and 4GB RAM machine. When I start to use JS wrappers like SmartGWT or GWText the startup of the Hosted Mode and the GWT application becomes "very slow". When I switch

Hosted mode is a strange beast. most of the java code runs in hosted mode as java, and executes faster than it would in your browser (IE), but if you have to cross the java/javascript boundary then you end up with a pretty big performance hit where the code will execute much slower than in

If you are 1.38 gigs into swap then you need at least 1.38GB more RAM to keep your machine responsive... Anyone developing java in 2009 should really have at least 2 gigs of RAM. Anyone trying to run a Java IDE + a servlet container + a servlet + a browser +++ should really have at least 4GB of

Paul, I checked task manager. What I see is that when I run it in hosted mode the cPU usage shoots up to 88% and Page File Usage to 1.38GB. I have increased the PF size by 2GB. Still dont see much change. Maybe I need a higher RAM :( On Apr 28, 4:42 pm, Paul Grenyer wrote: > Hi > > On Tue, Apr
