comparing strace of single request through lighty-1.5-svn and nginx-0.5.10

[yusufg@…]

I used the following commands to capture the strace

system is Centos 4.4/x86-64

strace -f -o nginx.strace nginx -c conf/webserver.conf strace -f o lighttpd.strace lighttpd -D -f webserver.conf

both nginx/lighty configs are setup for epoll and sendfile. access/error log is disabled for both client is http_load -fetches 1 -parallels 1 file-containing-url

I can't figure out why lighty has open/stat of /etc/localtime whereas nginx doesn't have any also lighty-svn seems to open the file which is to be sent twice compared to nginx single time
