Mac OS Yosemite and Sophos for Mac ---slowing down my internet speeds

So I installed the newest version of Sophos for Mac onto my Mac Pro and iMac. I'm running latest version of Yosemite and after the install it slowed down my internet speeds. My download speeds were drastically affected, so I think uninstalled Sophos and my speeds were back to normal. Is there anything I can do to have Sophos running and my download speeds/internet speeds at their normal speeds? Please help asap.

Web Protection slowing down browsing has a number of posts on this forum. I've included a link below to one that discusses why some users may see the problem but not all.

DNS (taking a human-readable site name and looking up the IP address that tells your computer exactly where it needs to go to) can be slower for some users. When SAV has to look up a lots of addresses quickly, and domain name resolution is a bit slow, the browsing experience can be seen to be slow. Hence a pre-existing problem shows up. Note: It's not just one address that SAV has to look up. For example, if you load amazon.com it's not just one address. There are many many addresses the homepage (all pages on that site) connect to so the content loads in the sidebars etc.

If you don't get anywhere with investigating a slow DNS (the thread linked above has suggestions) you can choose to disable web protection. Websites you connect to are not checked but you would still benefit from on-access and on-demand scanning locally on your computer, so if malware tries to save itself/run from your mac you're protected - the web protection is just trying to stop it ahead of spotting it locally.
