we are migrating to a new system with web servers and a website.
The old system runs under WIN2008 servers and IIS and on physical nodes.
The new system runs under WIN2012R2 and IIS and on VMs.
The website is start itself is ok but when I log in to my personal place to see my bookings or want to book something, this is nearly 10 times slower.
What can I check to speed up the content requests from my SQL to my website ?
Do you have any ideas or tools to check ?
