Author performance issue

[yogesh_kumar]

We are facing page slowness while logging to the author page. we have done all the checks like (disk usage, memory, cpu and network traffic). No issues were found.

I am able to open CRX/DE pages fastly but having slowness only with the home.html

Please check the below error logs and let me know for any pointers. Is the performance issue occurs due to the application as well ?

Hi,

if you have performance problems on login of the page, this exception is hardly the root cause of it. As suggested, please qualify the slowness (especially which request is slow) and then use the recommended appraoch to check, if you can spot any hotspot in that specific request.
