Other Parts Discussed in Thread: TDA4VH
Hi,
Please refer to the url below for the history of this question.
Read speed should not be 1/3 of write speed - this is an anomaly. As an experiment, you could try read/write using SSD as an endpoint. This should automatically link to the nvme kernel module instead of the pci endpoint kernel module, and this should give you a better estimate of what read/write performance should be. |
We use a PCIe SSD as endpoint, and test the read/write performance. And the test result is as below.
It seems SSD read result is much better than using TDA4VH(about 2.4GB/s) as EP(about 700MB/s).
And SSD write result is a little worse than TDA4VH EP. (1.7GB/s to 1.9GB/s).
And what I want is
1. Your opinion about the test result?
2. What we want to do is enhance READ performance, is there any idea about how to do that?
Thank you.
