zkevm Configuration and TPS Measurement Concerns on Polygon Nodes

While following the Polygon documentation to run the zkevm node, I observed an unusual pattern on zkevm.polygonscan.com. It seems that most blocks only contain a single transaction. Was the zkevm originally designed to include just one transaction per block by intention? If that’s the case, I’d like to adjust my node’s configuration to allow more than one transaction per block to facilitate smoother TPS measurements. Can you guide me on which file and section I should modify?

Additionally, I’m trying to measure the Transactions Per Second (TPS) on the node I’ve set up. Despite searching multiple platforms, including GitHub, I haven’t identified a suitable method or tool for this purpose. If you’re knowledgeable about any tools or methods to measure TPS on L2 nodes, I’d greatly appreciate your guidance.
