IIUC, the default in the last release (and earlier?) started creating H2 worker threads in each prefork process. Generally, prefork is still used to run non-threadsafe plugins. If we don't create multiple threads, the H2 responses are done serially. Maybe it needs a backdoor to allow being re-enabled? -- Eric Covener cove...@gmail.com
