Would firmware-linux-nonfree bring any advantage as far as performance is
concerned? I don't have it installed, and everything works fine on my
machine, but I wonder whether I should consider installing it. I've just
installed intel-microcode since I feel it might have an impact.
When in doubt, try:
dmesg | grep -i firmware
and see if it complains about any files that it wants to load but can't.
From there, you can use packages.debian.org, or one of the IRC bots,
to track down which package contains your firmware file.
I only find something related to ACPI, which I don't understand whether
is significant:
~$ sudo journalctl -k|grep -i firmware
Sep 17 21:14:48 alan kernel: ACPI: [Firmware Bug]: BIOS _OSI(Linux)
query ignored
Sep 17 21:14:48 alan kernel: acpi PNP0A08:00: [Firmware Info]: MMCONFIG
for domain 0000 [bus 00-9b] only partially covers this bridge
And then a strange error message, it doesn't find a .txt file:

[...]
brcm/brcmfmac43602-pcie.bin is the firmware for my Broadcom BCM43602
wireless card, contained in package firmware-brcm80211. Without it the
wifi network adapter didn't work, so I provided it during installation,
and then that package was automatically installed. I don't understand
what's that brcm/brcmfmac43602-pcie.txt file, it complained about it
also during installation, but the wifi card works nevertheless.
So can I conclude that I wouldn't get any benefit by installing
firmware-linux-nonfree? And what about intel-microcode that I've just
installed? Can I expect some performance related benefit?
