Slow browser ( ie- firefox - chrome ) performance on Windows server 2012 r2 rds


I'm running into a problem with IE11 - Chrome -  Firefox running terribly slow through a RDS connection with Windows Server 2012 R2.

We have several customers that have slow performance when they browse with these browsers. The load time can be above 15 seconds. It takes forever to load the initial page.

Can somenone help me with this issue?

Sounds likes there are not enough resources available for the virtual instances like mem or vCpu's OR hdd load is way to high on the host.

What resources do you have and what do you give away to the virtual instances?

Where it is common to all, I always like to check DNS first.  If you use one of Goggle's IP's in the browser, as below, is there any improvement?

Hello everyone,


Ip loads very fast. Dns is not the problem. When i want to open a page like or the load time is above 15 seconds.

If opening a page by IP is very fast and opening using a URL is slow, I am not sure how you can say "DNS is not the problem"  DNS may be resolving but it may be an incorrect DNS configuration or slow DNS server as a forwarder.  All opening by IP does is avoid the use of DNS.
