# Optimize CME Package Performance

Improve high volume transaction processing with these performance tuning options for the CME managed package.

- **[Enable Rapid Attribute Configuration for Industries CPQ Cart in LWC](https://help.salesforce.com/s/articleView?id=ind.comms_enable_rapid_attribute_attribute_configuration_.htm&release=264.0.0&type=5)**  
    The rapid attribute configuration feature reduces the number of API calls when assigning attributes to products in the cart. With this feature, you can update multiple attributes and when you're done, run repricing and validation API calls by clicking **Update Cart**.
- **[GUIDs Performance](https://help.salesforce.com/s/articleView?id=ind.comms_guids_performance.htm&release=264.0.0&type=5)**  
    Salesforce made GUID performance enhancements to meet demand from customers for higher throughput for some key transaction types. The GUID performance feature is an optional performance enhancement feature.
- **[Performance-Optimized getCartsItems API Trim Mode](https://help.salesforce.com/s/articleView?id=ind.comms_performance_optimized_getcartsitems_api_trim_mode.htm&release=264.0.0&type=5)**  
    The getCartsItems API now includes Trim Mode to support high-scale transactions involving complex product bundles (200+ items). This feature optimizes the Industries Cart by delivering lightweight data payloads, preventing performance bottlenecks and system failures.
