Slowness on one of the environments
Hello,
I hope someone can help with our Performance issue.
We have two environment: UAT and SIT
First issue:
For the following scenario we are running a Performance Profiler: pressing down on an Autocomplete that reads from a data page D_ProjectIDList
Running a Performance Profiler for that scenario on UAT is taking twice as much time as running it on SIT.
After further investigation we noticed that Java steps are taking double the time on UAT. More specifically one of the OOTB activities such as Rule-Declare-Pages.pzGetProcessedClipboardData (whose method is JAVA) is taking 5.9 seconds on UAT and 2.2 seconds in SIT.
Note that both environments have the same Java VM Information.
We are attaching the file generated by the thread of D_ProjectIDList on both UAT and SIT.
Second Issue:
Running a Performance Profiler on UAT is showing a Thread PS1_TABTHREAD1 whose size is 1,137,907 although that thread is not present on SIT when we run the same scenario.
We are attaching the file generated by the thread PS1_TABTHREAD1 on UAT.
Same as for the first issue, the method of the activities causing the most wait time are JAVA; they are reaching up to 5.13 seconds.
Why can we only see this thread on UAT and not on SIT ? What is it exactly ?
PS: running a Database Tracer generated almost same result on both environments which made us conclude that the problem is on the application level.

Any help or hint will be greatly appreciated :)

You could do a private checkout of pzGetProcessedClipboardData and update the java step to see which portion of it is causing delay.

Hello Dheev,
Thank you for your reply.
There is no difference between the two instances.
Our latest discovery on the slow environment (UAT) shows that all the Data Pages have empty Usage references but this is not the case on the SIT environment.
Below is the UAT empty Usage for all data pages:
and below is the Usage appears correctly on SIT:
Can you please advise why the data page usage is empty on UAT? Could it be the cause of the slowness ?
Thank you in advance for your reply :)

This is a pagelist used to store other rules that use the Data_Page but wouldn't have an effect at run time as is your noted concern.
