Slow VPN between sonicwalls

I have a remote office which is connecting to the main office via a VPN between 2 sonicwall routers.  The main office uses a sonicwall tz-170 with standard OS and the remote office uses a sonicwall tz-180 with standard OS.  I am able to see the main office side, but my transfer speeds are VERy slow.  I have a T1 a the remote office and 2-T1s at the main office.  I have set VPN bandwidth management on the remote router at a gauranteed 1000kbps and a maximum 1200kbps and also set the main office side at a gauranteed 1000kbps and a maximum 1200kbps, both with a highest priority of 0.  Even with this, it still takes me 27 minutes to transfer a 215MB folder.  No, I am not trying to transfer files that large all the time, I was using that folder as a testing benchmark.  I know it won't be as fast as the main network, but I should at least get that transfer down to 5 minutes or so, right?

Guys,

I appreciate your help and input.


Digi,

Thanks for the steps you outlined.  I will take a look at those and make any changes I can that you suggested.  That will help eek out every second of speed I can get.


Jimmy,

After some testing later in the day and some quick calculations, I figured out exactly what you are saying.  It is good to hear from someone who knows more about WAN connections than I do.  I found out that it takes about 10 seconds to open a file while at the corporate site and that same file opened over the WAN takes about 15 minutes.  Since the corporate site is running on at least 100MBPS and the WAN at around 1MBPS, my math says the corporate site should be about 100 times faster than the WAN.

I am splitting the points since you both helped by either pointing out steps or clarifying what expectations i should have.

Again, thanks very much!!!!!
no problem.  glad we could help and thanks for the points!
