US 2019/0163538 A1 · PERFORMANCE TUNING OF VIRTUAL RESOURCES

Abstract

A set of techniques is described for enabling a user of a virtual resource to specify to the hosting system a preferred performance parameter such as throughput, latency, CPU utilization, or the like. The hosting system then dynamically tunes the underlying resources to favor the preferred performance parameter. Tuning the settings may include adjusting various batching and moderating processes that are available on the hosting device, such as enabling/disabling interrupt coalescing, enabling/disabling segmentation offload, increasing or decreasing the size of a ring buffer used to share data between several resources, batching input/output (I/O) operations and the like. For example, if the user has indicated that lower latency is preferable, the hosting system may disable interrupt coalescing; whereas if the user has indicated that higher throughput should be favored, the hosting system may enable interrupt coalescing.

Dependent claims

A computer implemented method comprising:

under the control of one or more computer systems configured with executable instructions,
provisioning a compute node for a user on a resource stack;
executing a workload on the compute node;
analyzing runtime information associated with the workload being executed on the compute node;
determining, based at least in part on analyzing the runtime information, whether to configure the resource stack for either higher network throughput or lower network latency, and
modifying one or more settings for at least one resource in the resource stack to configure the resource stack for either higher network throughput or lower network latency as determined based at least in part on the analyzed runtime information.

A computer implemented method for tuning performance settings in a virtualized computing environment, said method comprising:

receiving a request for a virtual machine instance from a user;
provisioning the virtual machine instance on a resource stack;
receiving, from the user of the virtual machine instance, information indicating a performance parameter for at least one resource of the resource stack, the performance parameter indicating a threshold for either high throughput or low latency;
