# Oracle Cloud Performance Tuning ## Overview Navigate OCI's opaque shape naming, block volume performance tiers, and shape-dependent network bandwidth. OCI shapes like `VM.Standard.E5.Flex`, `VM.Standard3.Flex`, and `VM.Standard.A1.Flex` look similar but have wildly different performance profiles. Block volume tiers (Balanced, Higher Performance, Ultra High Performance) have different IOPS and throughput limits that are easy to get wrong. This skill maps performance characteristics to shapes and storage tiers so you can make informed infrastructure decisions. **Purpose:** Choose the right compute shape and storage tier for your workload by understanding OCI's performance characteristics, and monitor those resources programmatically. ## Prerequisites - **OCI tenancy** with an API signing key in `~/.oci/config` - **Python 3.8+** with `pip install oci` - **Compartment OCID** for querying available shapes and metrics - Basic understanding of IOPS, throughput, and OCPU concepts ## Instructions ### Step 1: Understand Shape Naming OCI shape names encode processor generation, type, and flexibility: | Shape | Processor | OCPUs | Network Gbps per OCPU | Best For | |-------|-----------|-------|----------------------|----------| | `VM.Standard.E5.Flex` | AMD EPYC 9J14 (Genoa) | 1–94 | 1 Gbps | General workloads (latest gen) | | `VM.Standard.E4.Flex` | AMD EPYC 7J13 (Milan) | 1–64 | 1 Gbps | General workloads | | `VM.Standard3.Flex` | Intel Xeon (Ice Lake) | 1–32 | 1 Gbps | Inte...
