We understand that some users may experience slower performance in their Salesforce Sandbox environments compared to their Production orgs. This is a common issue and is due to several technical and infrastructural reasons.
Below, we've summarized the key causes and provided helpful links for deeper insights.
⚙️ Key Reasons for Slow Sandbox Performance
1. Shared Resources & Different Infrastructure
Salesforce Sandbox orgs are hosted on different servers from Production orgs. These servers may be shared across multiple sandbox environments and have lower performance prioritization.

Sandbox vs Production performance
2. Cold Start & Caching Delays
If a sandbox has been idle for a while, it may take longer to “wake up.” This cold start effect causes delays when loading data or pages, as backend caches and metadata need to reload.

3. Org Throttling
Salesforce may throttle requests in Sandbox orgs. This means certain actions or processes are queued, especially during high-load times, and can take longer to process.

4. Network Latency
Sandboxes may be hosted on a Salesforce data center located farther from your region, increasing latency (i.e., the time it takes for data to travel between your system and Salesforce’s servers).
5. Heavy Customizations
Custom code, large record layouts, debug mode enabled, or extensive workflows/process builders may slow down page rendering in sandboxes, especially where processing power is limited.

✅ What You Can Do
Here are a few steps you can take to improve performance or rule out other issues:
Run the Salesforce Speed Test:
Salesforce Speed TestDisable Debug Mode (if enabled in Sandbox).
Clear Browser Cache or test in Incognito Mode.
Use a Lightweight Page Layout for testing performance.
