Kyle Ambroff-Kao 44a4bc5fd6 tcp: Remove sanity checks from BufferQueue in release builds Each TCPEndpoint has two BufferQueue members, one for the send queue and one for the receive queue. If DEBUG_BUFFER_QUEUE is enabled, then most methods of BufferQueue call BufferQueue::Verify(), sometimes twice. This member function performs some sanity checking which requires iterating through every net_buffer in the queue. Disabling this in a debug build improved throughput by a factor of 5x over the loopback interface on my laptop. Using iperf the measured throughput went from 900Mbps to around 4.8Gbps. This patch turns this sanity checking off for release builds. * Rename DEBUG_BUFFER_QUEUE to DEBUG_TCP_BUFFER_QUEUE * Change the default in BufferQueue.h to disabled * Set DEBUG_TCP_BUFFER_QUEUE to KDEBUG_LEVEL_2 in kernel_debug_config.h Change-Id: I262dac5d7e2889d2942bbdcf6b667cc0cbafa4c8 Reviewed-on: https://review.haiku-os.org/c/haiku/+/2780 Reviewed-by: waddlesplash <waddlesplash@gmail.com>		2020-05-23 02:32:58 +00:00

Haiku

Homepage | Mailing Lists | IRC Channels | Issue Tracker | API docs

Haiku is an open-source operating system that specifically targets personal computing. Inspired by the BeOS, Haiku is fast, simple to use, easy to learn and yet very powerful.

Goals

Sensible defaults with minimal configuration required.
Clean, clear, concise code.
Unified desktop environment.

Trying Haiku

Haiku provides pre-built nightly images and release images. Haiku is compatible with a large variety of hardware, but in case you don't want to "take the plunge" and install Haiku on bare metal, you can install it on a virtual machine (VM) instead. If you've never used a VM before, you can follow one of the "Emulating Haiku" guides.

Compiling Haiku

See ReadMe.Compiling.

Contributing

Haiku is a meritocratic open source project with a large variety of tasks. Even if you can't write code, you can still help! Haiku needs designers, (technical) writers, translators, testers... Get involved and help out!
