Suggestions to improve client performance

Some of our users are complaining Clearwell is running slow on their computers. I did a test, on my laptop I am getting the following results:

• Logging onto Clearwell: 3 seconds  (clicking signing in to dashboard)
• From an employee list record to all cases: 2 seconds

When I tried the same on users computer, I get these:

• Logging onto Clearwell: 10 seconds
• From an employee list record to all cases: 8 seconds

I am thinking this is something to do with IE or Flash settings on the endpoint. Are there any online documention or previous experience that I can use to troubleshoot client performance issues?

Thank you
