For a custom backup application running in Windows with low throughput, what configuration change is recommended to enhance performance?

1. Add 4GB of memory to the VM.

2. Span the 2TB disk across four vDisks.

3. Increase the number of cores per vCPU.

4. Increase the vCPUs assigned to the VM.

The correct answer is: Span the 2TB disk across four vDisks.

To enhance performance for a custom backup application running in Windows with low throughput, spanning the 2TB disk across four vDisks is recommended. This approach improves performance by allowing the application to utilize parallel processing and I/O operations. When a larger disk is segmented into multiple smaller vDisks, data can be read and written simultaneously across those disks, reducing contention for I/O bandwidth and increasing overall throughput. By distributing the workload across multiple vDisks, the backup application can take advantage of multiple paths for data flow, resulting in faster read/write speeds compared to accessing a single, large disk. This is especially beneficial in a backup scenario, where accessing and processing large amounts of data is crucial for timely operations. The other suggested configurations, while potentially beneficial in certain contexts, may not directly address the specific throughput issues faced by the application in this scenario.
