Hi,

How did you measure your performance? What do you mean by slow? Slow server or UI or what?

Hi,
I can see that the module polymer of my cuba app is slow in production environment because On the homepage take it more time to load, . . . . . . . . I can see the network requests on the homepage is 307 and take it more tan 10 seconds!!.. I attach a screen shot !!!

inicioRequest

I think it is so much!!!. . . . . I have read in polymer framework web that the network requests can reduce it using a tool call Vulcanize but this tool is not work it in my cuba app, . . . would you know how could solve this problem? . . cuba framework offers a solution about this problem . . it is really importan to me because the develop is done but now I see it is not Optimized for production!!!

Thank a lot

I look forward to your answer!

Hi,

What build preset do you use?
For production it’s recommended to use es5-bundled preset.

#8

on the other hand, when I try to create the war using “preset”: “es5-bundled”, with the task buildWarPro of build.gradle it´s created a war es6-unbundle rather than es5-bundled, would I have to point something in the task buildWarPro to create a war es5-bundled???

attach screenshot

thank a lot!!

task buildWarPro of build.gradle

warBuildPro

Polymer.json

polymerClient

it´s created a war es6-unbundle

warUnbundle

There is a polymerBuildDir property of CubaWarBuilding, you need to change it to es5-bundled
