# Performance
#### Mechanism
* **Tools Used**: PACT (Apxor’s in-house performance monitoring tool)
* **Benchmarking candidate**: Firebase SDK
* **Duration of each run**: 10 minutes
* **Total no. of runs**: 10
#### Impact on App Size
| S.No. | Description | App Size |
| ----- | ----------------- | --------------------- |
| 1 | Standalone App | 3.8 MB |
| 2 | App + NudgesSDK | 4.55 MB **(+750 KB)** |
| 3 | App + FirebaseSDK | 4.6 MB **(+800 KB)** |
#### CPU Bechmarking
The following matrix consists of **Device vs %CPU consumed**
| Device | Standalone App | App + ApxorNudgesSDK | App + FirebaseSDK |
|---|
OnePlus 3
(Android 9) | 23.12 | 31.6 | 49.08 |
OnePlus 7
(Android 10) | 8.62 | 10.70 | 12.43 |
Xiaomi Mi A1
(Android 9) | 24.23 | 30.40 | 35.94 |
Xiaomi Mi A3
(Android 10) | 6.69 | 8.25 | 7.52 |
**Note** On an average, for the high end devices (OnePlus 5 and above) with ApxorNudgesSDK integrated, CPU usage would increase by **2%** while with FirebaseSDK it would increase by **4-5%** .
In low end devices with ApxorNudgesSDK integrated, CPU usage would increase by **8%** while for firebase the CPU usage would increase by **20%**.
#### Memory Bechmarking
The following matrix consists of **Device vs Memory Usage in KB**
| Device | App + ApxorNudgesSDK | App + FirebaseSDK |
|---|
OnePlus 3
(Android 9) | 24.84 | 28.92 |
OnePlus 7
(Android 10) | 24.62 | 29.38 |
Xiaomi Mi A1
(Android 9) | 18.10 | 24.18 |
Xiaomi Mi A3
(Android 10) | 20.11 | 26.90 |
**Note** For ApxorNudgesSDK with all the plugins installed, the memory increases by **30 KB** which is on par with the Firebase SDK that has seen an increase by **29 KB**.
#### Battery Usage Bechmarking
The following matrix consists of **Device vs %Battery Drain**
| Device | Standalone App | App + ApxorNudgesSDK | App + FirebaseSDK |
|---|
OnePlus 3
(Android 9) | 0.15 | 0.19 | 0.29 |
OnePlus 7
(Android 10) | 0.03 | 0.05 | 0.05 |
Xiaomi Mi A1
(Android 9) | 0.18 | 0.23 | 0.32 |
Xiaomi Mi A3
(Android 10) | 0.12 | 0.13 | 0.13 |
**Note** For ApxorNudgesSDK with all the plugins installed on an average the battery drain % would be **0.03%** while with the FirebaseSDK installed it is recorded to be around **0.06%**.
