pageinfo.json is taking time to load

Hi All.

I am facing one issue related to page load when I looked at the network logs it is pageinfo.json which is taking more than 15 sec to load. It is badly impacting page and workflow package load. Is there any way to tackle this issue. I am using AEM 6.0 SP2, oak 1.0.12. Are there any indexes we need to create for this? We have less than 100 groups and users. All are OOTB workflows only two custom workflows.

Hi,

I cannot say, what the problem is, the threaddump does not indicate the number of calls to MongoDB. If course latency is an issue (always). Maybe you can check the number of requests in mongodb.

Hi Jorg,

Yah I tried with out mongo it seems relatively better. Is it because of the Process time it is taking in Mongo (If this is the case I can try by increasing Mongo specs)? or is it some network issue between mongo and AEM?

Hi,

looks like the time is spent on mongodb... I don't know if there are lots of calls or a very slow single call.

kind regards,
Jörg

Hi,

that's one option. The other one is a regular threaddump, see [1] for some recommendations.

kind regards,
Jörg

Thanks Jorg.

You are spot on. We are doing all the 3 activities as you mentioned. I am trying to take threaddumps from /system/console/status-Threads . Is this correct? or Can you please suggest .

Hi,

so it's not a filter, but the PageInfoServlet. Then there might be a number of things, which can cause the observed behaviour:

  • full replication queues (you should observe it then as well when browsing in the siteadmin, as it's getting really slow)
  • you are working a lot with MSM
  • lot of running workflows or workflow models

Can you do a number of threaddumps, when this request is running, and post only the relevant pieces of the stacktrace?

kind regards,
Jörg

Hi,

can you share the details of such a request as show by the "recent requests" screen in the OSGI console (/system/console/requests)? It will give some more insights, where the problem can originate from.

Thanks,
Jörg

Hi,

I know this thread is old. I can reproduce the same issue in 6.2 SP1. Did you got a solution for this? For us it is taking 18sec for the page info request.

Thanks
