The most important TCP tuning areas since kernel 4.9 are:
- packet pacing
- dynamic TSO sizing
- TCP small queues
- BBR TCP congestion algorithm
- Gb = gigabit
Notes to make IR shield (made by LinkSprite) work in Raspberry Pi 3 (bought from Amazon [1]). | |
The vendor has some documentation [2] but that is not complete and sufficient for Raspbian Stretch. | |
Following are the changes that I made to make it work. | |
$ sudo apt-get update | |
$ sudo apt-get install lirc | |
# Add the following lines to /etc/modules file | |
lirc_dev | |
lirc_rpi gpio_in_pin=18 gpio_out_pin=17 |
package main | |

LDAP24API = LooseVersion(ldap.__version__) >= LooseVersion('2.4') |
