With that commit applied I get net throughput of 10.5 MB/s, without that commit I get around 100 MB/s on my setup. > Thanks for the report. 6.2 has been out for quite some time, and this is the first such report. So I don't think there's a general problem. Can you please provide a full dmesg log and elaborate on the type of traffic and how you measure the speed? BTW: With 100MB/s you refer to 100MBit/s? Also interesting would be whether there are any errors or missed packets in the ethtool -S <if> output. Instead of commenting out this line you can also adjust the values from userspace: /sys/class/net/<if>/gro_flush_timeout /sys/class/net/<if>/napi_defer_hard_irqs Does increasing the gro_flush_timeout value change something for you? Somewhat strange is that lspci shows ASPM as disabled in LnkCtl, but L1 sub-states are enabled in L1SubCtl1. Do you have any downstream kernel code changes or any specific ASPM settings? > I've verified that just commenting out the one line in r8169_main.c > > ``` > --- a/drivers/net/ethernet/realtek/r8169_main.c > +++ b/drivers/net/ethernet/realtek/r8169_main.c > @@ -5505,6 +5505,8 @@ static int rtl_init_one(struct pci_dev *pdev, const struct pci_device_id *ent) > dev->hw_features |= NETIF_F_RXALL; > dev->hw_features |= NETIF_F_RXFCS; > > dev->pcpu_stat_type = NETDEV_PCPU_STAT_TSTATS; > > - netdev_sw_irq_coalesce_default_on(dev); > + //netdev_sq_irq_coalesc_default_on(dev); > > /* configure chip for default features */ > rtl8169_set_features(dev, dev->features); > ``` > > restores the speed with kernel 6.11.6.

BTW: With 100MB/s you refer to 100MBit/s? Nono, I mean 100MBytes/s ;-) My testcase is transferring a large file over SMB and looking at the transfer speed as reported by KDE. (I'm attaching a full dmsg of a boot of a 6.11.6 kernel with only irq_coalescing commented out otherwise as released.) > Also interesting would be whether there are any errors or missed packets > in the ethtool -S <if> output. No errors or misses in either patched or unpatched kernel. > Instead of commenting out this line you can also adjust the values from userspace: > /sys/class/net/<if>/gro_flush_timeout > /sys/class/net/<if>/napi_defer_hard_irqs > Does increasing the gro_flush_timeout value change something for you? That's cool. I've reverted to unchanged 6.11.6 and if I set napi_defer_hard_irqs to 0 I'm back to 100 MBytes/s. Playing with gro_flush_timeout while napi_defer_hard_irqs is set to 1 does not seem to have any effect on the trasfer speed. Default value is 20000. I have tried some values between 1000 and 200000. > Somewhat strange is that lspci shows ASPM as disabled in LnkCtl, but > L1 sub-states are enabled in L1SubCtl1. Do you have any downstream kernel code > changes or any specific ASPM settings? No. Other than patching the default value for interrupt coalescing, I'm running a vanilla kernel. Maybe it is because I didn't enable ASPM in the kernel configuration? Thanks for taking this up.

SMB file transfers are a standard use case, so I would have expected at least some complaints if performance drops to 10%.

I've reverted to unchanged 6.11.6 and if I set napi_defer_hard_irqs to 0 I'm back to 100 MBytes/s. Playing with gro_flush_timeout while napi_defer_hard_irqs is set to 1 does not seem to have any effect on the trasfer speed. Default value is 20000.

So far I've not been able to find a BIOS setting that makes that warning go away. If you think, that the current settings are the best default values for most users, I'd defer your better knowledge of the hardware. At least I'm happy because I can get my performance back by disabling IRQ coalescing on a vanilla kernel. Regards Felix

Even 2.5Gbps works with full line speed on this system. OK, your CPU is even weaker, but this still shouldn't cause such a performance drop. More the opposite, as software interrupt coalescing reduces the CPU load. However there's nothing special with your system, according to the dmesg log. > Regards > Felix Heiner

The terminology in the iperf output is from the perspective of the client machine. So leporello's transmit performance suffers almost 9-fold with interrupt coalescing (the drop I had been measuring with my GUI tests), while its receive performance "only" drops 3-fold. Regarding ASPM I've now tried all possible settings in my BIOS. I can still not make the warning go away. The above measurements are with ASPM disabled in my BIOS. Regards Felix

Hi there, commit 42f66a44d83715bef810a543dfd66008b883a7a5 to Linus' kernel tree ("r8169: enable GRO software interrupt coalescing per default") introduces a speed regression on my hardware. With that commit applied I get net throughput of 10.5 MB/s, without that commit I get around 100 MB/s on my setup. I've verified that just commenting out the one line in r8169_main.c ``` rtl8169_set_features(dev, dev->features); ``` restores the speed with kernel 6.11.6. Is there perhaps a more elegant way to fix this regression for other people too? Regards Felix This is my lspci -vvxx output: ``` 03:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd.
