Hi Etienne,
Thanks for adding to the wiki! As we migrate the website it will become
our official documentation source as its easy for people to update, so
feel free to add, tinker and amend.

Thanks Chris,
It does not seem like I have permissions to create a page for the
results. I can't get any link on the page you sent which gives me that
option. I am logged in...
Sorry, maybe I am missing something obvious...

Thank you Etienne, this is great. I would appreciate you putting up a
wiki page at:
https://cwiki.apache.org/confluence/display/OODT/Home
That captures this information and helps folks to collaborate if you
have time. If you need permissions on the wiki space just register for
CWIKI at Apache and tell me your username I¹ll grant you permissions.
As to having a config file in OODT PushPull to set the buffer size,
there isn¹t one (it relies on whatever the underlying operating
system uses - so like you found out if you are on Linux flavors, the
solution you present below is a good way to set this).
HTH!
Cheers,
Chris

Subject: OODT buffer size
Hi Shakeh,
Hope all is well!
I am still busy with evaluating OODT... Currently I am exploring the
tool
using different TCP transfer window sizes. I done this by editing
/etc/sysctl.conf and setting the variables
net.core.rmem_default
net.core.rmem_max
net.core.wmem_default
net.core.wmem_max
I have attached the results I found for varying the transfer window on
both the client and server.
However, I was unable to found an OODT configuration file to set the
buffer size. Is there such file where I can do this?
Thanks!
