Slow Start Problem

[denizg]

I am using cas overlay template (6.2.0).  the cas server will be ready too late (almost in 1 minutes), but that's not my real problem. when the screens are opened for first time, the responses are slow, and the first actions on the screens respond late. 

For example, I open login screen for first time, it responds in 10-15 seconds.

I enter my crendetials for first time, it responds in 10-15 seconds.

i think it's not about computing power because i have good system (intel i7 cpu and 32 gb ram). i have tried to change jvm memory (overlay comes with 2gb, i increased it to 8gb for example. nothing changed), tried to remove lazy initialization beans if any, but didnt found any directly related beans.

i am sure everyone has this problem. do you have a solution for this? 

thanks

Denizg,

On my local, I might see an initial delay of at most 2s. Java does just in time compiling, so initial access to some things will include compile time.

You can set the loggers to debug for as many systems as possible (spring prints a LOT of logs) and see where the delays show up.

Another option is a VisualVM, to see what is going on with running java processes.

hey ray, thanks for response. 

i realized that when i use "standalone" in my active profiles, it works slow as i said. but when i remove, i dont have any speed/load problem. so i think, my problem is related about standalone profile.

what profiles do you use to start cas? (if you haven't set it, standalone profile is used by default)

Denzig,

We are using standalone, since we have no value set.

Could the speed issue be related to a background task that is reloading the config?

Our config is loaded on startup (I still have to look into on demand refresh), and I have not noticed any performance issues.

hey roy. which cas version you use? we are using 5.2.x in our legacy project and there is no performance issue there. but we are working on 6.2.x and above in new project, we come across problems i said.
