Lighttpd + fastcgi + python (for django) slow on first request
- by EagleOne
I'm having a problem with a django website I host with lighttpd + fastcgi.
It works great but it seems that the first request always takes up to 3seconds. Subsequent requests are much faster (<1s).
I activated access logs in lighttpd in order to track the issue. But I'm kind of stuck.
Here are logs where I 'lose' 4s (from 10:04:17 to 10:04:21):
2012-12-01 10:04:17: (mod_fastcgi.c.3636) handling it in mod_fastcgi

Server: lighttpd/1.4.28
I guess that if there is a problem, it's whith my configuration. So here is the way I launch my django app:
python manage.py runfcgi method=threaded host=127.0.0.1 port=3033
And here is my lighttpd conf:
server.modules = (
"mod_access",
"mod_alias",
"mod_compress",
"mod_redirect",
"mod_rewrite",
"mod_fastcgi",
"mod_accesslog",
)
server.document-root = "/var/www"
server.upload-dirs = ( "/var/cache/lighttpd/uploads" )
server.errorlog = "/var/log/lighttpd/error.log"
server.pid-file = "/var/run/lighttpd.pid"
server.username = "www-data"
server.groupname = "www-data"
accesslog.filename = "/var/log/lighttpd/access.log"
debug.log-request-header = "enable"
debug.log-response-header = "enable"
debug.log-file-not-found = "enable"
debug.log-request-handling = "enable"
debug.log-timeouts = "enable"
debug.log-ssl-noise = "enable"
debug.log-condition-cache-handling = "enable"
debug.log-condition-handling = "enable"
fastcgi.server = (
"/finderauto.fcgi" => (
"main" => (
# Use host / port instead of socket for TCP fastcgi
"host" => "127.0.0.1",
"port" => 3033,
#"socket" => "/home/finderadmin/finderauto.sock",
"check-local" => "disable",
"fix-root-scriptname" => "enable",
)
),
)
alias.url = (
"/media" => "/home/user/django/contrib/admin/media/",
)
url.rewrite-once = (
"^(/media.*)$" => "$1",
"^/favicon\.ico$" => "/media/favicon.ico",
"^(/.*)$" => "/finderauto.fcgi$1",
)
index-file.names = ( "index.php", "index.html",
"index.htm", "default.htm",
" index.lighttpd.html" )
url.access-deny = ( "~", ".inc" )
static-file.exclude-extensions = ( ".php", ".pl", ".fcgi" )
## Use ipv6 if available
#include_shell "/usr/share/lighttpd/use-ipv6.pl"
dir-listing.encoding = "utf-8"
server.dir-listing = "enable"
compress.cache-dir = "/var/cache/lighttpd/compress/"
compress.filetype = ( "application/x-javascript", "text/css", "text/html", "text/plain" )
include_shell "/usr/share/lighttpd/create-mime.assign.pl"
include_shell "/usr/share/lighttpd/include-conf-enabled.pl"
If any of you could help me finding out where I lose these 3 or 4 s. I would much appreciate.
Thanks in advance!
