Hi,
Back with a question (or two). I am testing the performance of our web2py
app. To get to the root of what is happening, I executed uwsgi with one
worker and straced the process. In the output, I see a lot of data like -
"
stat("/var/www/web2py/gluon/ast", 0x7fff540a5050) = -1 ENOENT (No such file
or directory)
open("/var/www/web2py/gluon/ast.so", O_RDONLY) = -1 ENOENT (No such file or
directory)
open("/var/www/web2py/gluon/astmodule.so", O_RDONLY) = -1 ENOENT (No such
file or directory)
open("/var/www/web2py/gluon/ast.py", O_RDONLY) = -1 ENOENT (No such file or
directory)
open("/var/www/web2py/gluon/ast.pyc", O_RDONLY) = -1 ENOENT (No such file
or directory)
..
Is this expected?
I also see a lot of stuff like -
"stat("/var/www/web2py/applications/everest3/languages/my.py",
{st_mode=S_IFREG|0775, st_size=8210, ...}) = 0
stat("/var/www/web2py/applications/everest3/languages/nl.py",
{st_mode=S_IFREG|0664, st_size=16825, ...}) = 0
open("/var/www/web2py/applications/everest3/languages/nl.py", O_RDONLY) = 9
fstat(9, {st_mode=S_IFREG|0664, st_size=16825, ...}) = 0
flock(9, LOCK_SH) = 0
fstat(9, {st_mode=S_IFREG|0664, st_size=16825, ...}) = 0
lseek(9, 0, SEEK_CUR) = 0
fstat(9, {st_mode=S_IFREG|0664, st_size=16825, ...}) = 0
mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) =
0x7fdeee172000
lseek(9, 0, SEEK_CUR) = 0
read(9, "# coding: utf8\n{\n'!langcode!': 'nl',\n'!langname!':
'Nederlands',\n'\"update\" is an optional expression like
\"field1=\\'newvalue\\'\". You cannot update or delete the results of a

16384) = 16384
read(9, "py': 'Welkom bij web2py',\n'Welcome to web2py!': 'Welkom bij

applicatie aanpassen naar je eigen behoeften',\n'You visited the url %s':
'Je bezocht de url %s',\n}\n", 4096) = 441"
Does all this happen for every request?
Can I remove many languages from the folder and reduce the 'overhead'?
