-// A CryptoMbPrivateKeyMethodConfig message specifies how the CryptoMb private
-// key provider is configured. The private key provider provides `SIMD`
-// processing for RSA sign and decrypt operations (ECDSA signing uses regular
-// BoringSSL functions). The provider works by gathering the operations into a
-// worker-thread specific queue, and processing the queue using `ipp-crypto`
-// library when the queue is full or when a timer expires.
-// [#extension-category: envoy.tls.key_providers]

-  // How long to wait until the per-thread processing queue should be

-  // already in the queue are processed, even if the queue is not full.
-  // In effect, this value controls the balance between latency and
-  // throughput. The duration needs to be set to a non-zero value.
