Tally is a powerful accounting tool for businesses, but it can sometimes run slower than expected. Understanding the causes and implementing the fixes can save time, increase productivity, and ensure smooth operations. In this guide, we’ll explore the top 10 reasons why Tally is getting slow and how to resolve each issue efficiently.
1. Large Data Files
As your business grows, the Tally data file size increases, slowing down performance. Large files take longer to process and load.
Fix:
- Split data by financial year and archive older data.
- Navigate in Tally: Gateway of Tally → Alt+Y (Data) → Split → Split Data.
- Select the company, set the date, and proceed.

2. Outdated Tally Version
Older Tally versions may not be optimized for speed and can cause performance issues.
Fix:
- Update to the latest Tally version.
- Check for updates in the Tally application or on the official Tally website.
3. Too Many Users Logged In
Multiple users logged in simultaneously can overload the server and slow Tally.
Fix:
- Limit concurrent users.
- Upgrade to a version or server setup that handles more users efficiently, like Tally Server 9.
4. Corrupted Data
Corrupted files can make Tally slow or crash due to improper shutdowns or hardware issues.
Fix:
- Use Tally’s data verification and repair tool: Gateway of Tally → F1 (Help) → Troubleshooting → Repair under Company Data.

5. High System Resource Usage
High CPU or memory usage affects Tally performance.
Fix:
- Close unnecessary programs running in the background.
- Upgrade hardware: add RAM or use an SSD for faster access.
6. Network Issues
Poor connectivity slows Tally, especially in multi-user setups.
Fix:
- Ensure a fast and stable network.
- Prefer wired connections over Wi-Fi.
- Upgrade network hardware if needed.
7. Antivirus Scanning
Real-time scanning can slow Tally by scanning files continuously.
Fix:
- Exclude Tally folders from antivirus real-time scanning.
8. Fragmented Disk
A fragmented hard drive delays file access.
Fix:
- Run disk defragmentation regularly.
- Optimize SSDs with appropriate tools.
9. Excessive Backups
Improperly scheduled backups can interfere with Tally operations.
Fix:
- Schedule backups during off-peak hours.
- Use automated backup solutions that run at night.
10. Heavy Customizations
Extra plugins or complex customizations increase load and slow performance.
Fix:
- Review and remove unnecessary customizations.
- Optimize or streamline essential customizations.
- Consult your Tally service provider for guidance.
