Performance
Wireshark is known for its resource-intensive nature, particularly when performing real-time packet capture and analysis. This can be demanding on both CPU and memory, especially in high-traffic networks.
Resource Usage
Running Wireshark can consume significant system resources, which may impact the performance of the capturing system.
Operating System Differences
There can be variations in performance between different operating systems. For instance, capturing packets on a Linux system might yield different results compared to a Windows system, due to differences in system overhead and driver efficiency.
Accuracy
The accuracy of Wireshark’s timestamping is a critical aspect, especially in applications requiring precise measurements.
Timestamp Accuracy
The accuracy of timestamps can vary depending on the system and hardware used. For example, capturing on a high-end router might provide reliable data down to 100 microseconds, while on a regular PC or virtualized system, the accuracy might be limited to around 1 millisecond.
System and Hardware Variability
The variability in bus clock regularity and system overhead can introduce inconsistencies in timestamp accuracy. This means that while Wireshark can capture and timestamp packets quickly, the underlying system’s capabilities can limit the precision of these timestamps.
Limitations and Areas for Improvement
Several limitations and areas for improvement have been identified:
Ease of Use
Wireshark has a steep learning curve and can be overwhelming for beginners due to its depth of information and range of features. Improving the user interface and adding more prepopulated filters could enhance usability.
