Problem Note 37787: Slow performance is possible with million draw, massive proxy scenario t-copula VaR simulations
 |  |  |  |  |
If you run t–copula VaR simulations in SAS® OpRisk VaR, you might experience long run times if both of the following conditions are true:
- you specify a large number of draws (for example, one million)
- you are using proxy scenarios for sub–business lines and sub–risk categories
There is no workaround.
