Possible Causes

It's probably due to the time it takes to draw to all the charts. Maybe we should each spawn goroutine.

ali/gui/drawer.go

Lines 66 to 84 in 2711e42

valuesP50 = appendValue(valuesP50, res.P50)
d.widgets.percentilesChart.Series("p50", valuesP50,
linechart.SeriesCellOpts(d.widgets.p50Legend.cellOpts...),
)
valuesP90 = appendValue(valuesP90, res.P90)
d.widgets.percentilesChart.Series("p90", valuesP90,
linechart.SeriesCellOpts(d.widgets.p90Legend.cellOpts...),
)
valuesP95 = appendValue(valuesP95, res.P95)
d.widgets.percentilesChart.Series("p95", valuesP95,

@yzwdroid Yup, I hope you'll give it a try :D

LineChart.Series seems to be the biggest bottleneck, so we need to make sure that this does not block the process.

ali/gui/drawer.go

Lines 59 to 64 in 2711e42

d.widgets.latencyChart.Series("latency", values,
linechart.SeriesCellOpts(cell.FgColor(cell.ColorNumber(87))),
linechart.SeriesXLabels(map[int]string{
0: "req",
}),
)

ali/gui/drawer.go

Lines 67 to 69 in 2711e42

d.widgets.percentilesChart.Series("p50", valuesP50,
linechart.SeriesCellOpts(d.widgets.p50Legend.cellOpts...),
)

For instance, it might be good to call this at the interval specified as redrawInterval.

@yzwdroid I'm so sorry, but it's a critical issue so I've addressed it. It would be nice if you help me another time.
