Speed up EMC and Powershell when working on a LAB


  1. Disable CRL Checking (only if you don’t have internet access)
        • Decreasing the amount of time to allow CRL retrieval can significantly improve performance when internet access is poor or non-existent. Setting the value to 200 decimal (milliseconds) may be a reasonable timeout.
    • Name: ChainRevAccumulativeUrlRetrievalTimeoutMilliseconds
      Location: HKLM\SOFTWARE\Microsoft\Cryptography\OID\EncodingType 0\CertDllCreateCertificateChainEngine\Config
      Type: REG_DWORD
        • Decreasing the amount of time to allow all CRL retrievals can significantly improve performance when internet access is poor or non-existent. Setting the value to 500 (milliseconds) may be a reasonable timeout.
