RQM Scaling and Performance

We are designing a RQM solution and are interested in knowing if it can scale  and performance with our solution.
We expect that the maximum number of concurrent users will be 20.

Here are the numbers:
Total Number of Test Case – 10K, Total TCER – 3.38M,  Total TCR - 6.9M
  Continuous Testing - 6500 TCs
    Weekly Iterations (for 3 years)
      Test Case Executions Records – 3*52*6500 = 1.014 million
      Test Case Results (average 2 runs / TC / Week) – 3*52*6500*2 = 2.028 million
  Life Cycle Testing - 7500 TCs
    Weekly Iterations (for 3 years)
    3 Releases V11, V12, V13
      Test Case Executions Records – 3*3*52*7500 = 2.34 million
      Test Case Results (average 2 runs / TC / Week) – 3*3*52*7500*2 = 4.68 million
  Product Verification Testing - 7500 TCs
    2 month Iteration
      Test Case Executions Records – 7500
      Test Case Results (average 4 runs – 7500*6 = 45K
  MISC (Function Testing, Special driver testing, etc)
      Test Case Executions Records – 10000
      Test Case Results (average 4 runs – 10000*10= 100K
