Hello,
I am using the computer described by the following dmesg and I am not
able to find where is a limitation. I have an internet connection of
500 Mbps download. It is handled by a router, and my computer is
connected in the LAN. This link can be fully saturated on another
OSes, tested on the same computer, something around 490 Mbps or
60MBps.
On OpenBSD all downloads are limited somehow at aprox. 260Mbps or
30MBps. I am not sure if the network card is not able to sustain full
500Mbps download, nor the CPU or it might be that the disk is not able
to cope with such writing speeds. Application tested are firefox,
chrome, transmission.
Is there a method to check what part in this chain is not able to
sustain this operation?
Could be that some other causes are in the play?
Thank you.
