Have you done any custom modifications on q2a database like creating indexes?

---

I did not make any modifications to the database

Oh. I believe your eventlogger plugin might be on. Can you please try turning that off?

---

Where can I find the event log? Please explain the steps

---

Please help me with this, clarify where I can find the event log

---

Please help me, do you mean delete?
qa-plugin/ event-logger

---

In Admin/plugins/event-logger options you can see the option to turn it off.

1. Did you follow the advice above? (uncheck both checkboxes under "Administration center > Plugins > Event Logger > Options)
2. Have you tried disabling all non-default plugins? (some plugins can be disabled by unchecking their checkbox under "Administration center > Plugins,"  for others you may need to move the plugin directory out of the $Q2A_DIR/qa-plugins directory)
3. Have you tried profiling a slow operation with your browser's web development tools to identify the bottleneck? If so, what were the results?

1-Yes I uncheck both checkboxes under "Administration center > Plugins > Event Logger > Options


 2- Yes, I disabled all non-default plugins
 (I couldn't stop the default plugin)

 3- Unfortunately, I do not have the experience to identify the bottleneck
