Hi all when running the benchmark on my new component, the Integrity Digest Cache, I ran into a serious performance issue. The benchmark is extending a TPM PCR with 12313 entries of the IMA measurement list, and calculating the time elapsed for the operation. Without TPM HMAC: 102.8 seconds With TPM HMAC: 1941.71 seconds Do you have already an idea on how to improve the situation? Thanks Roberto
