18c394976e
runtime: disable the Nagle algorithm entirely.
...
See also commit feed91d; that commit fixed the test_rpc_timing test,
but caused frequent hangs elsewhere, which were also caused by buggy
Nagle implementation. Just disable this entirely, as with our
explicit buffering it provides no benefit anyway.
2016-11-13 00:33:24 +00:00
whitequark
feed91d8b2
runtime: buffer RPC send packets.
...
This brings mean RPC time from ~45ms to ~2ms.
The cause of the slowness without buffering is, primarily, that lwip
is severely pessimized by small writes, whether with Nagle on or off.
(In fact, disabling Nagle makes it function *better* on many small
writes, which begs the question of what's the point of having Nagle
there in the first place.) In practical terms, the slowness appears
only when writing a 4-byte buffer (the synchronization segment);
writing buffers of other sizes does not trigger the problem.
This all is extremely confusing and the fix is partly palliative,
but since it seems to work reliably and we're migrating off lwip
I think it is unwise to spend any more time debugging this.

runtime: don't print debug messages to the UART.
...
It takes ~4ms to print an empty log line because of how slow
the UART is. This makes the log timestamps useless for debugging
performance problems.
After this commit, it takes ~75us to print an empty log line instead,
which pessimizes test_rpc_timing by less than 2ms with tracing
enabled.

runtime: fix a race condition with async RPCs.

session.rs has code like:
while !rpc_queue::empty() {
try!(process_kern_queued_rpc(stream, &mut session))
}
// A
if mailbox::receive() != 0 {
try!(process_kern_message(waiter, Some(stream), &mut session));
}
If both an async and a mailbox RPC (async or large sync) are posted
at point A then they will be processed out of order.
This commit fixes the issue by flushing the async RPC queue before
posting any RPC to the mailbox.
