We're running Adobe AEM 5.6.1 Author (w/ Oracle JDK 1.7.0.79) and it became very slow to login and use today (reported around 3:50PM - though the numbers in sar indicate it may have started at 1:30PM). Restarting the app around 4:00PM seems to have fixed. sar reports high %user numbers during the slow performance, and low idle numbers (which indicate high CPU use?), but the load average history doesn't show high CPU load? Wondering if these stats shed any light onto the app performance? Does %user indicate user (Application) process stats? Our CMS runs with a dedicated user, wondering if %user corresponds to it possibly?
Thanks for any help in interpreting these statistics.
