Hi Aaron,

Comments:

 - It seems like the flash version in Safari and Firefox is limited in OSX.  Maybe its me, you can test my server from http://128.118.46.248:7123/.  I just did a rpm -Uvh to the 2 URLs below and rebooted this test server.

 - Chrome threw a warning about Flash and Upload was less the Safari and Firefox

 

Here is some testing I did.

From OSX:
Safari Java:
Up: 903.31 mb/s
Down: 941.33 mb/s


Safari Flash: 

Up: 832.42 mb/s

Down: 30.51 mb/s



Firefox Java:

Up: 877.66 mb/s

Down: 941.41 mb/s


Firefox Flash:

Up: 809.62 mb/s

Down: 30.55 mb/s



Chrome Java:

Up: 721.76 mb/s

941.38 mb/s


Chrome Flash: 

Warning: Using the flash client in Chrome may provide less accurate results

Up: 499.03 mb/s

Down: 919.25 mb/s



I have been downloading the ndt client for some time onto my laptop and run it from the CLI.  I scp /usr/ndt/Tcpbw100.jar to a directory, create a sub-directory called lib and download json-simple-1.1.1.jar.  Then I run

sudo java -jar Tcpbw100.jar t248.npidev.psu.edu 3001 

and get the following java GUI results:

Subject: Final(?) Release Candidate for NDT 3.7.0

Hi All,

We have the, hopefully, final release candidate for a new NDT release. This release candidate includes a number of fixes and changes since -rc1.

Among other things, version 3.7.0 will include:
  - A java client that works with Java 8
  - A flash-based client
  - A new web GUI
  - Support for using Apache instead of ‘fakewww'

This is a beta-test version, and is not recommended for general use yet. However, we're hoping that, with some testing in the community, this can be improved quickly and a production release can happen relatively soon. We're especially interested in feedback on how easy it is to use the various new tools, and features.

Tarball:

RH6/x86:


RH6/x86-64:

SRPM:

Cheers,
Aaron
