Foram,

To me all the evidence points to an issue with you network (slow site loading and poor map performance). Either there is something internal that is cause a bottleneck for uploading data or your provider is simply not providing you very good upload bandwidth. Have you run a tool like http://speedtest.net/ to get a general idea of what your upload speed is?

Thanks

but inside our network the speed is good but outside it is working slow.

I think it is something related to dsl.do you know how to check the issue?

Yes I understand that, which is why I think it is your upload speed (meaning the bandwidth you have to upload data to the internet) may be slow. Internally you probably have 10 MB/s or faster bandwidth. As I mentioned in my previous post go to a site such as http://speedtest.net/ and just click the Begin Test button it will show you a realistic estimate of both download and upload bandwidth to the internet. It is not uncommon for some ISPs to only give about 1/10 (or less) upload speed compared to what your download bandwidth is. So you may have a connection advertised as 15 mb/s (download) which is giving only 1 mb/s upload speed.

Hope that helps

Thanks Joe,

I test the speed and the result i got is download speed is 4.94 mbps and upload speed is 0.62 mbps.

Thanks
