# MailScanner Performance

### Hardware & Software

The ECS MailScanner currently runs on a Sun Ultra-5 and a Sun Ultra-10, both running Solaris 8.

### Graphs

I have various performance graphs which show the fact that it is happily extracting viruses without becoming clogged down by the load:

- ECS detection graph since installation
- Above graph, but with data plotted using 1-week sliding average
- Above graph, but with weekly instead of daily data
- Pie chart showing breakdown of viruses detected (and stopped) entering ECS

### Speed

However, as a specific example of the unpacking and scanning speed, the Sun Ultra-5 processed a 24 Mbyte message as follows:

Task | Start | End | Time
--- | --- | --- | ---
Sendmail receives message | 18:32:53 | 18:33:48 | 56 seconds
MailScanner unpacks and scans message | 18:33:59 | 18:34:25 | 26 seconds
Sendmail delivers message | 18:34:26 | 18:34:50 | 25 seconds
