<div dir="ltr">I am very curious about the oft quoted 5000 worker thread limit for varnish instances. Particularly:<div><br></div><div>1) Is this recommendation still best practice despite having been made years ago? Is it still relevant for -- now readily available -- beefier server configurations like 16 or 32 cpu monsters with hundreds of GB RAM and 10gb ethernet? Part of the original recommendation mentions bumping up against file descriptor limits, but a cr1.8xlarge ec2 cluster instance allows over 20m open file descriptors.</div>
<div>2) Is it the recommended limit for a single varnish instance, or a recommended limit machine-wide. For instance, if I'm running 5 varnishd instances on a single host, can each instance safely flex up to 5000 worker threads concurrently or should the sum of worker threads across all instances not exceed 5000?</div>
