Replying to [ticket:7707 nickm]:
> For non-TLS writes, the kernel should nagle for us, so we're probably
fine, though it might be sensible to impose a write threshold there too.
Nagle can't magically decrease latency of Tor network, so most of the
times exit relays rapids by data over internet.
Many Web servers can wrongly identify such behavior like slow HTTP attack
made by Slowloris software (https://en.wikipedia.org/wiki/Slowloris). Most
effective way to stop attack is to drop connection. Everyone can see such
defence right now if using TBB. Tor surfing becomes very pain full.
