# 效能測試 - Plot time consumpsion of do_request function
###### tags: `linux2020` `web server`
### 步驟
1. 分別對兩種 web server 丟出十萬次 request，每一千筆取樣一次（共100次）分別存到 `uring.txt` 與 `epoll.txt`
3. 透過腳本繪圖: `$ gnuplot plot.gp`
4. 檢視圖片: `$ eog performance.png`

#### Plot script `plot.gp`

set term png font "Verdana, 12"
set title "Time consumpsion of do\\_request func.'
set xlabel "experiment"
set ylabel "time (sec)"
set output "performance.png"
set xtic 10
set ytic 0.01

plot [:][:0.25] "uring.txt" using 1:2 with points title 'io\_uring', \
"epoll.txt" using 1:2 with points title 'epoll'
