Operating System Module

Broad Operating System Support

All current versions supported: Windows Client 11/10; Server 2022/2019/2016

All current platforms supported: x86*, x64, ARM*, Arm64

Brand new benchmarks: “Crypto-Processor (TPM) Cryptography”, “Internet DNS”, “Overall Internet”, “Overall Software VM (SVM) Java/.Net” benchmarks.

Crypto-Processor (TPM) Benchmark

Benchmark the cryptographic performance of the crypto-processor (TPM).

Measure the random number generator, hashing (SHA, etc.), encryption/decryption (AES) bandwidth. See our recent article: Crypto-processor (TPM) Benchmarking: Discrete vs. internal AMD, Intel.

Internet DNS Benchmark

Benchmark the performance of the DNS service.

Measure the latency of both cached and un-cached DNS queries to local and remote DNS servers.

Internet Overall Score

A combined performance index all Internet benchmarks (Connection (Bandwidth/Latency), Peerage (Bandwidth/Latency) and DNS (cached/un-cached Query Latency).

Rate the overall performance of your Internet connection.

Overall Software VM (.Net/Java) Score

A combined performance index all software VM engine benchmarks, .Net (CLR) Arithmetic, Multi-Media and Java (JVM) Arimetic and Multi-Media.

Rate the overall software VM (.NET/Java) performance of your processor(s)

Brand-new hardware information modules: “Crypto-Processor (TPM)”, “Biometrics” (fingerprint, etc. sensors, “Virtual Machines” (Hyper-V), “Storage Spaces” (software RAID), “SQL Servers” (database servers).

Crypto-Processor (TPM)
