TimeXtender 20.10.15.64 Performance

Good Morning,

We have recently upgraded TimeXtender to version 20.10.15.64. Both in QA and PROD servers. We have TX ETL jobs that extract data from Oracle database server to both server every night. They run at different times.

However, the PROD ETL job takes longer to extract data. QA ETL job takes quicker.

1. QA TX on average takes 3hours to extract data from PROD oracle.

2. PROD TX on average takes 5 hours or more to extract the same information from PROD Oracle. Sometimes this take longer than this.

3.PROD TX sometimes hangs the whole night.

4. PROD TX has higher specs than QA.

5. We have checked the Performance Indicators  on PROD server while PROD TX is running. The CPU, Memory and other indicators seems well.

6. We trying to figure out why performance on PROD is slow during the data extraction from Oracle.

We have checked all necessary indicators to and we still don't have answers.

Is there anything that you can advice us to check so we can understand why PROD is slower than QA or hangs sometimes as compared to QA?

Also please note even before the upgrade this was happening when we had version 17.1 x for 2018.

Any advice will be appreciated.
