Hi teor

That advice is quite sensible in my opinion and should be incorporated into tor mainline. With the recent load spikes, I've always wanders why is there a need for that may MB or even GB of queue memory. If it can't be retransmitted in few seconds, it will be retransmitted by source and will increase the queues further...

The current setting for maxmeminqueue is 256MB and will correct itself if lowered. I would suggest to make that value rate dependent, either configured or measured.

 To your knowledge, was there any thought put into such a dynamic config, instead of fixed percentage of free memory, independent of the actual throughput?
