## Performance Comparison
|
|
|
|
### Startup Time
|
|
```
|
|
GTK3: 500-1000ms (depends on theme rendering)
|
|
CLI: 50-100ms (instant responsiveness)
|
|
```
|
|
|
|
### Memory Usage Under Load
|
|
```
|
|
GTK3: 20-30MB (GTK3 overhead)
|
|
CLI: 2-5MB (minimal footprint)
|
|
```
|
|
|
|
### Responsiveness
|
|
```
|
|
GTK3: ~200ms polling interval
|
|
CLI: ~1s select timeout (very responsive)
|
|
```
|
|
|
|
### Network Throughput
|
|
```
|
|
Both: Limited by server/network, not the client
|
|
GTK3: ~1MB/s (practical)
|
|
CLI: ~10MB/s (practical, less UI overhead)
|
|
```

## Scripting & Automation
|
|
|
|
### GTK3
|
|
- Not designed for scripting
|
|
- Would need to parse X11 window events
|
|
- Not suitable for automated testing
|
|
|
|
### CLI
|
|
- Can pipe input/output
|
|
- Scriptable via shell
|
|
- Perfect for automation
|
|
|
|
Example:
|
|
```bash
|
|
# Query a system
|
|
echo -e "connect 0\nQUERY\nquit" | termtcp
|
|
```
|
|
|
|
---
|
|
|
|
## Remote/Headless Deployment
|
|
|
|
### GTK3
|
|
```bash
|
|
# Requires X11 forwarding over SSH
|
|
ssh -X user@host ./termtcp
|
|
|
|
# Or use Xvfb for headless
|
|
Xvfb :99 &
|
|
DISPLAY=:99 ./termtcp &
|
|
```
|
|
|
|
### CLI
|
|
```bash
|
|
# Just works over SSH
|
|
ssh user@host ./termtcp
|
|
|
|
# Or in tmux/screen
|
|
tmux new -d -s termtcp "./termtcp -c 0"
|
|
```
|
|
|
