Application Performance is Not as Expected

Several factors can impact application performance:

  • Available bandwidth

    We recommend that you use bare metal Compute instances because instance bandwidth scales with the number of oCPU's. Bare metal Compute instances provide the greatest bandwidth. Virtual machines (VMs) are bandwidth limited based upon the number of CPU’s consumed. Single oCPU VM Compute instances provide the least bandwidth.

  • Latency

    Accessing the File Storage service from an instance running in the same availability domain minimizes latency.

  • Mount options

    By not providing explicit values for mount options such as rsize and wsize, the client and server can negotiate the window size for read and write operations that provide the best performance.
