`LoadReport`

LoadReport(
    sent: int = 0,
    responses: int = 0,
    timeouts: int = 0,
    errors: int = 0,
    duration_s: float = 0.0,
    latencies_ms: list[float] = list(),
    response_codes: Counter[str] = Counter(),
)

Results of a load run. Latencies are in milliseconds.

`throughput`

Responses per second.

`percentile()`

def percentile(p: float) -> float

Latency percentile (nearest rank), e.g. percentile(95).

Functions

`run_load()`

async def run_load(
    make_client: Callable[[], ISO8583Client],
    count: int,
    concurrency: int = 10,
    connections: int = 1,
    network: CardNetwork | None = None,
    make_message: Callable[[int], ISO8583Message] | None = None,
) -> LoadReport

Send count requests with at most concurrency in flight, spread over connections. Parameters

Callable[[], ISO8583Client]

required

Creates a (not yet connected) client

int

required

Number of requests to send

int

default:"10"

Maximum requests waiting for a response at once

int

default:"1"

Number of TCP connections to spread requests over

CardNetwork | None

default:"None"

Card network for the generated sample messages

Callable[[int], ISO8583Message] | None

default:"None"

Builds request i. Defaults to sample authorizations with unique STANs.
