我用lighttpd+fastcgi托管的django网站有问题。 它工作得很好,但似乎第一个请求总是需要3秒钟。后续请求要快得多(<;1s)。在
为了跟踪这个问题,我在lighttpd中激活了访问日志。但我有点卡住了。在
以下是我“丢失”4s的日志(从10:04:17到10:04:21):

我想如果有问题,那就是我的配置。下面是我启动django应用程序的方法:
^{pr2}$这是我的lighttpd配置:
server.modules = (
"mod_access",
"mod_alias",
"mod_compress",
"mod_redirect",
"mod_rewrite",
"mod_fastcgi",
"mod_accesslog",
)
server.document-root = "/var/www"
server.upload-dirs = ( "/var/cache/lighttpd/uploads" )
server.errorlog = "/var/log/lighttpd/error.log"
server.pid-file = "/var/run/lighttpd.pid"
server.username = "www-data"
server.groupname = "www-data"
accesslog.filename = "/var/log/lighttpd/access.log"
debug.log-request-header = "enable"
debug.log-response-header = "enable"
debug.log-file-not-found = "enable"
debug.log-request-handling = "enable"
debug.log-timeouts = "enable"
debug.log-ssl-noise = "enable"
debug.log-condition-cache-handling = "enable"
debug.log-condition-handling = "enable"
fastcgi.server = (
"/finderauto.fcgi" => (
"main" => (
# Use host / port instead of socket for TCP fastcgi
"host" => "127.0.0.1",
"port" => 3033,
#"socket" => "/home/finderadmin/finderauto.sock",
"check-local" => "disable",
"fix-root-scriptname" => "enable",
)
),
)
alias.url = (
"/media" => "/home/user/django/contrib/admin/media/",
)
url.rewrite-once = (
"^(/media.*)$" => "$1",
"^/favicon\.ico$" => "/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"
如果你们中有人能帮我找出我丢失这3或4秒的地方,我将不胜感激。在
更新:还有一个信息。我激活了fastcgi日志,得到了以下两个fcgi日志之间的3s延迟:
2012-12-01 18:18:12: (mod_fastcgi.c.3636) handling it in mod_fastcgi

也许它与fastcgi配置有关?在
提前谢谢!在
有没有可能你的网站没有太多的活动?我认为在下一个请求之前,python解释器将从内存中删除。你有足够的内存来存储你所有的软件吗?是否还有其他任务在运行,可能会把python从内存中推出来——可能只是维护,或者邮件服务器?在
