I spent a lot of time getting Wan Opt to work in a lab and also did 2 onsite demonstrations. There are several ways to deploy it.
WAN Opt does a really good job of speeding up web browsing. Let' s start with that. It does a great job of it. So, you should turn that on if you have enough storage on your 60C flash drives. By the way, be careful what firmware you' re running. Too new and the WAN opt. options go away in the GUI.
Wan Opt does a poor job of speeding up file access. Let' s continue with that. Yikes. Under perfect conditions, it will make the 3rd 4th or 5th file copy of the same file go much faster. I also tried doing the same WAN Opt speed tests with a Forticlient installed and properly licensed for client side CIFS (Windows file sharing) and got poor results. So, without much further ado, here' s what you should expect:
For Fortinet WAN Opt:
- For Windows file copy (SMB/CIFS) you can see a *decrease in bandwidth used* but generally no speed increase - this may be enough for you
- occasionally you' ll see a speed increase, but that' s few and far between
- when the GUI in the 60C says you' re getting awesome speed increases in CIFS, you' re actually having login problems and the Windows clients are unable to login or access shares. This is clearly a bug in the CIFS acceleration in the FG.
- MAPI acceleration doesn' t work that well, don' t bother for modern outlook clients (encryption on or off, it just doesn' t make that much difference), but older 2000 Outlook seems to be a little faster
So what' s a guy in your position to do:
- Windows 2008 R2 server, enable SMB v2 anywhere you can
- Windows 2008 R2 branch cache should be on, since it is a client side cache and file check out system, it will be better than a network solution
- Windows 7 clients, use SMB v2 anywhere you can
- for high impact sites, set up a BranchCache server
Hope this helps.
