Re: Handling requests to an upstream that is unresponsive.

+1 on the problem :) We’ve often had very similar production issues too! A related issue here that plays a role in all of this mechanism is server session pools and the fact that ATS only marks a server down on a “connect failure”. In particular, when ATS tries to reuse an existing idle connec

Handling requests to an upstream that is unresponsive.

I would like to propose a change to how TS handles unresponsive upstream destinations. The current logic is * If there is a round robin, skip elements that are down. * Attempt to connect. * If the connect fails, and the upstream is marked down and within the down server cache time, restrict the

Re: Tentative proposal: TS mutexes should be queues not OS mutexes

I assume thread affinity can't literal mean no lock contention. You'd need a lock on the thread run queue wouldn't you? Continuations can't only get queued for the event thread from the event thread. I don't think we can say conclusively that there would be a significant difference due to lock c

Re: Tentative proposal: TS mutexes should be queues not OS mutexes

Do you have any more specific information on mutex contention? We have in fact already looked at doing this, I think back in 2015 with Dan Xu. The goal there was to have queues with the mutexes to avoid rescheduling. As a precursor Dan did some profiling and the only significant lock contention he
