I'm measuring throughput between two hosts. I use genode running on fiasco.OC on one machine and monolithic Linux on another machine. There's 82579LM NIC on each host. I'm running netperf_lxip.run script. As acpi driver doesn't work on my machine i'm using pci_drv driver. Another problem is that level-triggered interrupts are not recieved and i'm polling interrupts in the internal cycle in /os/src/lib/dde_kit/interrupt.cc: while (1) { _lock.lock(); if (_handle_irq) _handler(_priv); _lock.unlock(); }
//while (1) { //_irq.wait_for_irq(); /* only call registered handler function, if IRQ is not disabled */ //_lock.lock(); //if (_handle_irq) _handler(_priv); //_lock.unlock(); //} I've done the same thing while testing l4re network stack and it didn't affect performance then.

Hello!
I'm running netperf TCP_STREAM and TCP_MAERTS tests for lxip stack and i obtained extremely low result - 5x10^6 bits/s while the maximum throughput is 1000 mbit/s . I wonder what could be the reason for that.
That is only 5 mbit/s, which is indeed pretty low. Right now the LXIP stack should at least do about 500 mbit/s in either direction. Please let me know what hardware platform you are using, so I can try to reproduce the behavior.
Thanks,
Sebastian
