When I restart tor with that option enabled I get:
" 2014-10-02 00:52:38,199 [WARNING] Obfsproxy (version: 0.2.3) starting up. 2014-10-02 00:52:38,199 [INFO] Entering server managed-mode. 2014-10-02 00:52:38,200 [INFO] No transports launched. Nothing to do."
I noticed it says version 0.2.3 starting up.
$obfsproxy --version gives me O.2.12
Why is tor starting the old version? This must be the reason it is not working since scramblesuit was only rolled into obfsproxy in version 0.2.6 .
How do I get $sudo service tor start

It has nothing to do with the location (US). There are fewer US exit relays than other countries in Europe.
Check the CPU usage too, usually CPU is the bottleneck on high port speed servers. Tor does not know yet how to do multithreading.
Do you have AES-NI hardware acceleration at your CPU? This is very helpful too.
Install htop (yum -y install htop) and it will tell you exactly how much each core is used. Let us know. I see that you confirm CPU load is not the fault, but probably you are checking it via a tool which is reporting the usage for ALL CPU (all cores) - try with htop and see if there is just one core @ 98% usage and others at less than 10%.
If the CPU is not the bottleneck, there is something at your provider (probably throttling Tor traffic to balance the other non-tor users in the same datacenter). If you built the network infrastructure there and know for sure such thing is not implemented there, don't really know what to say. CPU / RAM and Network interface is all you can test to see if it is the bottleneck for Tor. If all these are off the list, there is something upstream you.
I repeat, the location is not the fault here, and I encourage adding more exits in the US.

Hi.
I am trying to enable Scramblesuit for my bridge. I am wondering if there is a method to verify that it is working, similar to how obfs3 shows "registered server transport". There is not much out there about scramblesuit but there is one mention that the log should show "
registered
server transport scramble suit".
Tor version is 0.2.5.8-rc
Obfsproxy version 0.2.12

Is there something wrong with my config?
One way to figure out if scramblesuit is running would be to enable logging, like this:
ServerTransportPlugin scramblesuit exec /usr/bin/obfsproxy --log-file /var/log/tor/scramblesuit.log --log-min-severity info managed

Ok, I got scramblesuit working. Had to change various permissions and copy over the new obfsproxy Dir from /usr/local/bin to /usr/bin/.
The log file helped; thank you! And just to confirm, I did receive a " server transport registered scramblesuit" entry in my log. On Oct 1, 2014 7:00 PM, tor-relays-request@lists.torproject.org wrote:
