Wildfly 10 taking long pause while start up

[boda.prakash]

Hi,

I have my application deployed over Wildfly 10.0.0 Final. I am working on reducing startup time of my application server which is more than 15 min right now.

When I start the server it takes long pause while creating some content into HOME\standalone\data\content folder.

I read some about content folder and found that it stores crash recovery data into this folder. I feel its to much time while booting server.

I have pasted initial logs I am getting while starting server, from 17:30:46,398 its taking 3 min to load content folder.

Please guide me how can I reduce this time taken by Wildfly? Do let me know if I am doing some mistake.

Did you try not using deployments folder and deploy via CLI or console?

this way it shouldn't scan the directories and deployment start should be almost instantaneous.

Hi Tomaz Cerar,

Thanks for your quick response.

We usually don't deploy it using CLI or console. We used to do the same thing in 6.1.0 EAP and it was not taking this initial pause.

My main concern is whatever it is doing in data folder. Its copying some content into standalone\data\content.

I am not sure what this content is but its huge in size around ~900 MB and that is what taking around 3 mins.

I just wanted to check if I can avoid this delay.

Thanks,

Prakash
