40k&#x2F;sec http requests (no pipelining) per core is about as fast as it gets unless you move TCP into user space.<p>Reports of &quot;millions per sec&quot; are usually talking about messages on established channels across all CPUs.<p>If you&#x27;re actually aware of a java based web server that can beat even 150k http requests measured by wrk or similar on local host I&#x27;d like to see it.
