I used Python instead of a shell script of-course. :-P

========================================================================
#!/usr/bin/env python3

import time

from urllib.request import urlopen


server = 'http://localhost:8080'
urls   = [
    '/',
    '/static/css/default.css',
    '/static/JavaScript/angular.js',
    '/static/appPublishedPhotos.js',
    '/links/data',
    '/versionPython',
    '/versionSQLite',
]
for x in range(0, 10):
    start_time = time.time()
    for url in urls:
        print(url)
        urlopen(server + url).read()
    end_time = time.time()
    print('It took {0} seconds\n'.format(end_time - start_time), flush = True)
    time.sleep(20)
========================================================================

It is not perfect code, no error checking and the last sleep is
superfluous, but for the current job good enough.

I have included the output as attachment. It is clear that bottle is
not the problem: fetching all the data takes at most 0.017 seconds.
