Note: The names of all files that are read or written during the trace will be included in the trace file. You can use the open-sourced application UIforETW to record the trace files. You can securely share your trace with Chrome engineers by following the instructions below.
Traces might contain sensitive data, such as process names or parameters and DLL function names or filenames. Event Tracing for Windows (ETW) collects performance information from all running processes during a specified time period. If you can’t identify the process that’s causing high CPU usage with a process manager, try recording performance event traces and sharing them with Chrome engineers. Or, Chrome browser is rendering a graphics-intensive page, such as a website with 3D images or YouTube videos. The graphics processing unit (GPU) process slows down if there’s an issue with a particular graphics card driver.Isolate Chrome browser tabs and identify which web apps or webpages are reducing browser performance.
CPU usage for the renderer process increases if you run web apps that aren’t well programmed.The main process slows down if disk access is slow or there’s not enough system memory available.If you don’t see the -type parameter, the process is responsible for all disk and network access and user interactions.Ĭommon scenarios that reduce browser performance include: For example, the -type=renderer process is responsible for one or more tabs or extensions that are currently in use. In Process Explorer, you can see command-line parameters to verify the type of Chrome browser process that’s running.
Use Windows Task Manager or another process manager, such as Process Explorer, to identify processes with high CPU usage.ĭetermine the type of process that makes Chrome browser run slower.
