- **WAMR_BUILD_SHRUNK_MEMORY**=1/0, default to enable if not set
> Note: When enabled, this feature will reduce memory usage by decreasing the size of the linear memory, particularly when the `memory.grow` opcode is not used and memory usage is somewhat predictable.
## **Instruction metering**
- **WAMR_BUILD_INSTRUCTION_METERING**=1/0, default to disable if not set
> Note: Enabling this feature allows limiting the number of instructions a wasm module instance can execute. Use the `wasm_runtime_set_instruction_count_limit(...)` API before calling `wasm_runtime_call_*(...)` APIs to enforce this limit.
## **Combination of configurations:**
We can combine the configurations. For example, if we want to disable interpreter, enable AOT and WASI, we can run command:
