\n ## Line Chart: Average CPU Usage During zk Generation Stages ### Overview This image presents a line chart illustrating the average CPU usage (%) across different stages of zk (Zero-Knowledge) generation. The x-axis represents the stages, and the y-axis represents the average CPU usage as a percentage. A single data series, labeled "cpu (%)", is plotted as a red line. ### Components/Axes * **X-axis Title:** Stages of zk Generation * **Y-axis Title:** Average CPU Usage (%) * **X-axis Labels (Stages):** compile, phase\_two\_initiation, power\_of\_tau, solidity\_verifier, verify\_proof, z\_key * **Y-axis Scale:** Ranges from approximately 20% to 65%. The scale is linear with increments of 10%. * **Legend:** Located in the top-right corner. * Label: cpu (%) * Color: Red ### Detailed Analysis The line representing CPU usage exhibits significant fluctuations across the different stages. * **compile:** Starts at approximately 22%. * **phase\_two\_initiation:** Increases sharply to a peak of approximately 64%. * **power\_of\_tau:** Decreases to approximately 52%. * **solidity\_verifier:** Decreases slightly to approximately 50%. * **verify\_proof:** Decreases to approximately 48%. * **z\_key:** Increases to approximately 44%. Specifically: | Stage | Approximate CPU Usage (%) | | --------------------- | ------------------------- | | compile | 22 | | phase\_two\_initiation | 64 | | power\_of\_tau | 52 | | solidity\_verifier | 50 | | verify\_proof | 48 | | z\_key | 44 | The line generally slopes downward from "phase\_two\_initiation" to "verify\_proof", then slightly increases at "z\_key". ### Key Observations * The "phase\_two\_initiation" stage consumes the most CPU resources, peaking at approximately 64%. * The "compile" stage has the lowest CPU usage, at approximately 22%. * CPU usage remains relatively stable between "power\_of\_tau", "solidity\_verifier", and "verify\_proof" stages, hovering around 50%. * There is a noticeable drop in CPU usage from "phase\_two\_initiation" to "power\_of\_tau". ### Interpretation The chart demonstrates the varying computational demands of different stages within the zk generation process. The high CPU usage during "phase\_two\_initiation" suggests this stage is the most resource-intensive, potentially involving complex calculations or data processing. The relatively lower and stable CPU usage during "power\_of\_tau", "solidity\_verifier", and "verify\_proof" indicates these stages are less computationally demanding. The slight increase in CPU usage during "z\_key" might be due to finalization or output operations. This information is valuable for optimizing the zk generation process. Identifying the most resource-intensive stages allows for targeted optimization efforts, such as parallelization or algorithm improvements, to reduce overall processing time and resource consumption. The data suggests that focusing on optimizing "phase\_two\_initiation" would yield the most significant performance gains.
