VENOM: Mempool Capacity
$X(N)=\frac{\lambda N}{1+\sigma(N-1)+\kappa N(N-1)}$
Equation
$X(N)=(lambda N)/(1+sigma(N-1)+kappa N(N-1))$
| Measure | Description | Example |
|---|---|---|
| N | is a number of nodes | |
| X(N) | is throughput of the system of N nodes | 100 requests per second |
| λ | is a throughput of the system with one node X(1) | |
| σ | a coefficient of contention | σ=0.05 (5%) |
| κ | a coefficient of crosstalk | κ=0.02 (2%) |
