As mentioned in the previous patch, sending small packets as soon as possible leads to network packet overhead. Grouping related writes under corking appears to help everything but unencrypted Unix plain sockets. I tested with appropriate combinations from: $ nbdkit {-p 10810,-U -} \ {--tls=require --tls-verify-peer --tls-psk=./keys.psk,} memory size=64m \ --run

Slightly RFC, as I need more time to investigate why Unix sockets appeared to degrade with this patch. But as TCP sockets (over loopback to localhost) and TLS sessions (regardless of underlying Unix or TCP) both showed improvements, this looks like a worthwhile series.

In the recent commit 3842a080 to add SEND_MORE support, I blindly implemented the tls code as: if (SEND_MORE) { cork send } else { send uncork } because it showed improvements for my test case of aio-parallel-load from libnbd. But that test sticks to 64k I/O requests. But with further investigation, I've learned that even though gnutls corking works great for smaller

I am wondering if there are any apps affected by this bug (and perhaps keeping people from switching Unicorn). It''s a fairly esoteric case, so I probably won''t make another release until tomorrow (sleepy now, will probably screw something else up or realize something else is broken :) Anyways it''s pushed out to master and 1.1.x-stable in case people want^Wneed it

This can hide bugs in Rack applications/middleware. Most other Rack handlers/servers seem to follow this route as well, so this helps ensure broken things will break loudly and more consistently across all Rack-enabled servers :) --- This will be in the next release, so fix your applications/middleware before hand... lib/unicorn/http_response.rb | 2 +- 1 files changed, 1 insertions(+), 1

In the course of some work I have been doing for Revolution Analytics I have had the necessity of modifying the plm function so that it would not die halfway through fitting. In particular, I was able to more than halve the runtime (for my particular run) and improve its memory usage with three small modifications: 1.) Replacing throughout apply(X, 2, mean) with colMeans, similarly with

I'm a bit too busy nowadays because of school so I haven't had time to look at everyone's bug reports and some other mails. They're still marked as unread in my mailbox, so hopefully I'll get to them soon. And I don't mind you resend them if I don't answer in a few weeks :) Changes: - Fixed maildir syncing errors about wrong UIDs - Maildir was re-read all the time,

Here is the summary on predict when using an arima0 object: The arima0 object must be based on a time series vector. That is; x <- ts(xm1, frequency=12, start=c(1975,1)) x.ar <- arima0(x,order=c(1,1,1)) predict(x.ar,n.ahead=3) Thanks so much to Prof. Brian Ripley and David Brahm and other! Sincerely, Erin Hodgess

Any time we reply to NBD_CMD_READ or NBD_CMD_BLOCK_STATUS, we end up calling conn->send() more than once. Now that we've disabled Nagle's algorithm, this implies that we try harder to send the small header immediately, rather than batching it with the rest of the payload, which causes more overhead in the amount of actual network traffic. For interfaces that support corking (gnutls, or

...problems in this area? If I understand TCP_CORK correctly, it is not going to keep data from being sent when it can fill a TCP packet to the MSS of the current connection. If there is enough data in the kernel to fill a packet to the MSS, then it will not be delayed because the socket has not been uncorked yet. I don't see a difference with the application level buffering here. > You (Henri) want TCP_CORK, it seems, because of bugs in your target devices. I know our device can handle any size TCP frame (upto MSS), but it would certainly be more efficient if all frames were filled to MSS (536...
