Rsync slow as heck for everyone else???

I just loaded fbsd 6.1 in a VM and tried the exact same test. Unfortunately I am getting the exact same results. Anything we can do here to improve fbsd-Infrant rsync? This is darn near the entire reason I bought this thing!!

We'll take a look. Unfortunately we don't have a FreeBSD environment here, so we'll need to get that going first.

I have a tcpdump of a file transfer if you are interested in looking at it.

Any further help on this would be appreciated. I would prefer to use your product but I need a working solution to handle my production replication.

Thanks

Sure. You can PM me with a link if you want.

Can you tell me who is 10.227.1.120 and who is 10.227.1.11?
Do you capture it in Freebsd machine?

We found:
1. The tcp packets are all wrong checksum from 10.227.1.120.
2. Slower response from 10.227.1.120

1.11 is the NAS
1.120 is the FreeBSD client

Capture was done on the FreeBSD machine. I've tested on two other FreeBSD machines with different NICs (one of them being VMWare) and had the exact same result.

There is a consistant 100ms delay in freebsd side for each round. I guess it might be a delay ack thing in your freebsd machine, but I am not sure, you can find out by yourself.

And you don't use Jumbo Frame, right?

I was using Jumbo Frame for a while, but disabled it in this testing. After this is working I will be replicating over the Internet so Jumbo Frames aren't really relevant here. Any ideas why all of my FreeBSD installations would do this with your rsyncd, but not with other machines?

To compare, you need to make another capture for rsync with other server. So we can see what is the difference inside.
