We have an accounting software that works on MySQL DB. To make it run better, we got a new powerful server and put two VMs on it. One with DB and another one with RDS.
When I try to run our application via UNC path from the DB machine, it works great. But when I try to run the same on RDS server, it took about 3-6x more time to start.
I turned off firewall and antivirus software, and don't know what should I do next. Machines as is work great, we have no issues.
I tested entirely clean machine and I don't get any startup lag. I even installed terminal server on that machine to see what happens, and all is the same. I followed every step I did on other server and got better results, meaning I can't replicate.
Is there a way to see/measure what is happening with the program and LAN when I am trying to start the app?
