InitialContext taking long time, any tips to speed-up?

[spadafora]

Hello,
from my test I notice a big difference for creating an InitialContext:

- from inside the server itself but 2 different vm: 350 ms. (somehow ok)
- from a remote client in the same subnet: 2.5 sec! (kind slow!!)
- from a remote client over the internet: up to 25 sec!! (horrible!!!)

Any possibility to reduce those numbers?
What can be the problem?
My LAN has a DNS (the default one from MS 2003 Server) but i tried using IPs instead of machine names with no changes in the results. the one from internet did use a static ip and not a domain name.

help appreciated,
thank you.

Hello,
yeah, I have heard of that...
but I don't know what can be wrong on my dns (or my provider ones)...
I don't know where and how I can improve this behaviour as it works very fast for common http calls, to download a file from my jboss using a dump servlet it takes nothing! I also tried to use Http Jndi but the result is the same, or even slower.
Can you help please?

thank you.


Note: WebLogic is much faster in these circumstances.
