Reduce Server Lag Caused by Console Spam

Understand the Performance Impact

The MC-271325 bug causes your server to continuously write error messages to the console and log files. This excessive I/O operation can create noticeable lag, especially on servers with many players or frequent disconnections.

How This Mod Helps

Disconnect Packet Fix Mod eliminates the root cause of these errors, preventing:

• Constant disk writes to log files
• CPU overhead from exception processing
• Memory buildup from stored error messages
• Console thread congestion

To see the improvement:

1. Monitor your server's TPS (ticks per second) before and after installing the mod

2. Note any reduction in server lag during peak player activity

3. Check your logs folder size—it should grow much more slowly

Players may notice smoother gameplay, fewer server stutters during mass disconnections, and faster server response times. The performance gain is most noticeable on servers that experience frequent player turnover or network instability.
