How to set the initial window size on PFSense?

  • It's now become popular to set the initial TCP send window to something larger then the default to speed initial page loads.  Google and all the other biggies are doing it.

    Any way to set PFSense to do this?  I know it's actually freebsd so perhaps a sysctl or something?

  • You're probably looking to do it in the wrong place. Unless you have something like Squid setup where the firewall actually initiates traffic, the firewall has no control of that, has to be done on the actual source device.
