Hi,<br>The interruptThresholdRate module parameter allows you to control the maximum number of interrupts/sec for an e1000 Intel NIC for example. Is there an equivalent parameter for Infiniband NICs. I am using a Mellanox Infiniband NIC. Please let me know if you need any more information.
<br><br>Noticed from a simple netperf TCP_STREAM test that I get around 50-80K interrupts/sec and my machine gets very unresponsive. Want to control the maximum number of interrupts that are generated by the NIC. Quick look at the code showed that there is a way you can use the notify* functions in the driver to let ipoib module know when a certain number of packets are received instead of notifying for every packet received. Is that something in the lines of what will achieve my goal?
<br>Any help/pointers are welcome.<br><br>Thanks<br>harish<br>
