Is this a Windows or Linux based system? What version of PostgreSQL? What
else is running on the server?

Subject: [ADMIN] High system CPU usage during query run




I have a problem with my database that I cannot fugure out. We have queries
running on the server and we observe that the sytem CPU% usage goes to 97 -
98% and the quries take tremendous amount of time to finish. On other days
the queries would run quick and the system CPU usage percentage is low.


We have done disk scans and did not find issue as per the sys admin. What
from the database perspective I should investigate to resolve the issue?


Our server has dual core Intel Xeon processors 2.66 GHZ, 16GB RAM and RAID10
1.5 TB.


Please I need advise on this problem.
