[omniORB] Corba slow

[Jingdong Sun]

Thanks, Johnny.

Looks like my DNS and reverse DNS set up alright (by my general checking). 
But please let me know if you have anything specific in mind.

Do you think if it may due to RH 7 network behavior changing?
https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/7/html/7.0_Release_Notes/chap-Red_Hat_Enterprise_Linux-7.0_Release_Notes-Networking.html

Shall I upgrade omniORB 4.1.6 (the release I am using) to a later version? 
It is hard for me to upgrade with my product, but wonder if this is 
necessary.

Thanks.

Hi,

This sounds more like a network problem, do you have DNS and reverse DNS
setup correctly?
