Hi,

Hello, I clicked myself a cheap vserver 20 days ago and it runs Tor since then. I mainly did this to play a bit with the relay, try around and so. I took over another relay a while ago, an exit, I don't want to try around on that.

It runs well, I got about 4,4 TB data up AND down since then, I have it running with 20-40Mb/s on a 100Mb/s connection (according to the hoster 100Mb/s), it runs as a non exit. CPU load it pretty high all the time according to arm it's about 80-100%, but with htop I can see that only one core of the CPU is busy, the others are not.

I figured that the CPU is so busy because the vserver doesn't have AES-NI, which I confirmed by some command I run (forgot the command).

Did you ask them if you can get it ? I had a VPS a while ago and they said "we disabled that for compatibility reasons" but if you want it we will turn it on. And they did it for free :-)

So I thought I might wanna move that relay to another server, maybe at the same hoster to get higher data transfer.

What hardware specs do you have and is my assumption correct with the AES-NI being one part of the bottleneck?

It is the no. 1 bottleneck from my experience. I still hope that we are going to see the crypto-multithreading feature at some point in the future.
