Problemi prestazioni dalle ore 20 alle ore 23

Question

Good morning,
we have been noticing that for a few days now a performance problem has been occurring from 8pm to around 11pm,
of our EC2 instance with Windows, our server begins to process very slowly and then returns to normal for the rest of the day.
From the performance monitoring from the AWS panel everything seems to be normal, in fact in the evening the network load drops, even the CPU usage is always the same,
what we notice is the time for processing and compressing files on our server which instead of 80 seconds, takes up to 300 seconds,
so consequently a slowdown of all the performances of the machine.

we are waiting for advice on how to solve the problem
regards

Good morning! It sounds like you're experiencing a specific performance issue during the nighttime hours for your EC2 example. Here are some steps you may take to diagnose and doubtlessly clear up the hassle:

1. **Check Resource Utilization**:
   - Even even though the CPU and community load seem regular, investigate different metrics along with memory usage, disk I/O, and application-unique logs. Sometimes, high reminiscence or disk I/O can result in slowdowns.

2. **Application Logs**:
   - Review the logs of your software at some stage in the slow periods. Look for any errors or warnings that could suggest what's inflicting the slowdown.

3. **Scheduled Tasks**:
   - Verify if there are any scheduled obligations, backups, or protection jobs jogging during that point that could impact overall performance.

4. **Disk Performance**:
   - If your example makes use of EBS volumes, check the overall performance metrics for the volumes. High examine/write latencies or burst stability depletion may affect overall performance.

5. **Instance Type**:
   - Ensure that the instance type is suitable for your workload. You might keep in mind resizing to a more effective instance if resource constraints are obvious.

6. **Network Configuration**:
   - Even even though community load drops, check if there are any configuration troubles consisting of throttling, or examine safety organizations and network ACLs for ability issues.

7. **Antivirus/Firewall**:
   - Sometimes, antivirus or firewall software can carry out scans or updates in the course of off-peak hours, which could slow down the server. Check their settings to look in the event that they coincide with the gradual periods.

8. **Windows Updates**:
   - Ensure that Windows Updates aren't jogging at some stage in that point. You can alter the agenda for updates.

9. **Performance Monitoring Tools**:
   - Consider using greater designated overall performance monitor.
