# 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%)             	|

## Usage 

Start the entire process by executing our script entrypoint via `run.sh`

```bash

./run.sh

```

## Monitor 

```bash

./list.sh

```

### Prometheus

### Naive Adaptive 

```bash

ORIGIN_WORKTIME=2s CLIENT_ORIGIN=http://proxy:7000 PROXY_ADAPTIVE=true docker-compose up

```

#### Results

client sends 5 requests per second and receives between 2.4 rps and 2.7 rps (HTTP 200) 


proxy oscillates between 4 and 6 in-flight requests 


origin processes between 2.7 and 3 requests per second 


origin has served requests with average latency 2.2 seconds 


origin has served 50% of requests (50th percentile) within 2 seconds 


origin has served 99% of requests (99th percentile) within 3 seconds with periodic spikes
