Hi,
I want to measure throughputs like following cases.
- path connected by RING PMDs
- path connected by librte_vhost and virtio-net PMD
- path connected by MEMNIC PMDs
- .....
Is there anyone want to do same thing?
Anyway, I guess those throughputs may be too high for some devices like ixia.
But it's a bit pain to write or fix applications just for measuring.
I guess a PMD like '/dev/null' and testpmd application will help.
This patch set is RFC of a PMD like '/dev/null'.
Please see the first commit of this patch set.
Here is a my plan to use this PMD
+-------------------------------+
| testpmd1 |
+-------------+------+----------+
| Target PMD1 | | null PMD |
+---++--------+ +----------+
||
|| Target path
||
+---++--------+ +----------+
| Target PMD2 | | null PMD |
+-------------+------+----------+
| testpmd2 |
+-------------------------------+
The testpmd1 or testpmd2 will start with "start tx_first". It causes huge
transfers.
The result is not thuroughput of PMD1 or PMD2, but throughput
between PMD1 and PMD2. But I guess it's enough to know rough thuroughput.
Also it's nice for measuing that the same environment can be used.
Any suggestions or comments?
Thanks,
Tetsuya
