EDP take too much time

[yooouxin]

Is there an already existing issue for this?

• [X] I have searched the existing issues

Expected behavior

I found that the time taken by the SEDP protocol is not fixed,I tested on aarchlinux x86 PC,using examples/cpp/dds/ClientServerTest ,I add some code to calculate the time spent by SEDP.

And I write a script to run client 100 times,I found that SEDP sometimes will take 500ms,I don't know why this is.

Current behavior

SEDP take so much time,and i want to know the reason,in my real project,It can take up to several seconds.

Steps to reproduce

1. add time calculating code to examples/cpp/dds/
2. run server
3. run client 100 times
