1 | This test hangs under 5.0 kernels onwards. It appears to be caused by the commit in the kernel: | ||

7 | tcp: implement coalescing on backlog queue | ||
8 | |||
9 | In case GRO is not as efficient as it should be or disabled, | ||
10 | we might have a user thread trapped in __release_sock() while | ||
11 | softirq handler flood packets up to the point we have to drop. | ||
12 | |||
13 | This patch balances work done from user thread and softirq, | ||
14 | to give more chances to __release_sock() to complete its work | ||
15 | before new packets are added the the backlog. | ||
16 | |||
17 | This also helps if we receive many ACK packets, since GRO | ||
18 | does not aggregate them. | ||
19 | |||
20 | This patch brings ~60% throughput increase on a receiver | ||
21 | without GRO, but the spectacular gain is really on | ||
22 | 1000x release_sock() latency reduction I have measured. | ||
