- Gebraucht bekommt man die Solarflare ab und an günstig auf eBay, in neu ist die Edimax-Karte wohl am günstigsten.
- Sonnet Tech-Karten & macOS Catalina 10.15
… kann man entweder in …
- Thunderbolt2/3-Gehäusen
- Akitio
- SonnetTech
- …
… oder als PCIe-Karte in Käsereiben-Mac-Pro …
- MacPro1,1 (2006)
- MacPro2.1 („8-Core“, 2007)
- MacPro3.1 (Early 2008)
- MacPro4.1 (Early 2009)
- MacPro5.1 (2010-2012)
betreiben.
Netzwerk-Parameter
Verbessern der macOS-TCP-Kernel-Parameter:
sysctl -w net.inet.tcp.sendspace=2097152 sysctl -w net.inet.tcp.recvspace=2097152 sysctl -w net.inet.tcp.delayed_ack=2
Bei sehr alten macOS-Versionen (vor 10.11) prüfen, ob der 'maxsockbuf' mind. 4 MB groß ist:
sudo sysctl kern.ipc.maxsockbuf
Wenn er 'kleiner' ist, dann auf 4 MB oder 8 MB stellen:
sudo sysctl -w kern.ipc.maxsockbuf=4194304
oder
sudo sysctl -w kern.ipc.maxsockbuf=8388608
Die sysctls muss man noch in ein Script stecken, das man per launchd bei jedem Systemstart ausführen läßt – obige Befehle setzen das nur temporär, d.h. nach einem Neustart sind obige Parameter wieder auf Werkseinstellungen zurückgesetzt.
Weiteres Tuning für ein paar Prozent mehr: die MTU von 1500 auf 9000 Bytes stellen: Netzwerk-Kontrollfeld am Mac, unter Debian Linux in /etc/network/interfaces im Interface ein 'mtu 9000'). Allerdings muss der Switch hier mitspielen, sonst geht die Performance kräftig runter, nicht hoch.
