Describe the bug
I ran some tests in headless mode using CefBrowserHost::PrintToPdf with M132 on Windows and observed a significant performance degradation compared to M127, particularly on virtual machines. Is there an explanation for this? Could it be related to the removal of the alloy bootstrap in M128? Is there an option I can try to restore the performance from M127?

CEF's PrintToPdf is just a thin wrapper around the DevTools protocol Page.printToPDF. Most likely any performance regression will be in Chromium. You can test in Google Chrome / Chromium to see.
