Less internet speed

Question

We are replacing DELL SONIC WALL with SOPHOS XG 450.in sonic wall we are getting very good internet speed. But when we connect Sophos its very very slow. 
 while doing speed test I could see that there is a big difference in Sophos and dell sonic wall 
 following things are tried 
 1.removed all IPS,WEB filter ,application filter policies and advanced threat protection tried link speed test 
 We have two ISP leased lines with each 5 mbps bandwidth. I want to do equal load sharing with two links 
 Kindly suggest recommend weight for both ISP and how can i solve the slowness issue.

Hi Nayan, 
 Check #4 in my troubleshooting guide to troubleshoot slow browsing. Show us the results to investigate the issue. Alongside, as the ISP connections provide equal bandwidth then define equal weight as 1 for both the links. 
 Finally, verify the throughput received directly on the XG firewall. Take SSH to XG and go to 5. Device Management > 3. Advance Console and execute, 
 wget http://speedtest.ttml.co.in/files/5M.exe 
 Thanks
