Struct CheckpointSerializationBaseline 

pub struct CheckpointSerializationBaseline {
    pub entry_count: usize,
    pub serialize_us: u64,
    pub deserialize_us: u64,
    pub tolerance: f64,
}

Checkpoint serialization performance baseline.

Fields

entry_count: usize

Number of history entries

serialize_us: u64

Expected serialization time in microseconds

deserialize_us: u64

Expected deserialization time in microseconds

tolerance: f64

Tolerance factor

Implementations

impl CheckpointSerializationBaseline

pub const ENTRIES_1000: Self

Baseline for 1000 entries.

Measurement Methodology

These values are derived from benchmark tests that:

1. Create checkpoint state with 1000 execution history entries
2. Measure serde_json::to_string() serialization time
3. Measure serde_json::from_str() deserialization time
4. Run multiple iterations to get representative average

Tolerance Rationale

Serialization performance varies significantly based on:

• CPU architecture and speed
• Memory bus speed
• System load (other processes)
• Compiler optimizations (debug vs release)

We use 2x tolerance (100% headroom) to avoid false positives while still catching catastrophic regressions (e.g., O(n²) algorithms).
