# Discovery resource utilization

# Discovery resource utilization {#ariaid-title1}

Release version: Brazil  
Updated September 10, 2026  
![](https://www.servicenow.com/docs/portal-asset/ico-clock) 2 minutes to read  
Standard transactions on Windows and UNIX generate various amounts of network traffic, depending on what is being discovered.
These tables show the bandwidth consumption for each data flow segment of a typical
discovery using probes and patterns over different operating systems.

[Table 1. Discovery Bandwidth Over Different Operating Systems (in Megabytes)]

{#discovery-resource-utilization__table_vxx_sdk_dfc}

The following table shows the bandwidth comparison between an initial discovery for three-tier applications and for each subsequent discovery. Bandwidth is broken up into the three tiers: UI (Apache), application (Websphere), and data (Oracle). This measures the total data transfer for each discovery run once for a device class.

[Table 2. Discovery Bandwidth for Three Tier Applications (in Megabytes)]

{#discovery-resource-utilization__table_vxx_sdk_dfd}

This table shows discovery of different OS types using patterns. This measures, in
megabytes, the total amount of data created and the total amount of data in subsequent
scans for each device.

[Table 3. Discovery Bandwidth for Patterns over Different Operating System Types (in Megabytes)]

{#discovery-resource-utilization__table_xnh_yjk_dfc}  
Note:  
These measurements were taken with base operating configurations. Your local system results may vary.

## CPU Usage examples

Examples from CPU Usage will vary among the matrix of thousands of combinations of Operating Systems, chip sets and specific loads for each system.

Your mix of these variables will determine your unique level of CPU consumption.

Use internal templates to identify unique builds. Monitor the performance impact that Discovery has on your system.
