map v/s rewrite performance

March 25, 2014 04:12AM
Hi All,

I am just wondering, say for 1000 url redirects, what will be more efficient.

Rewrite Style:
============
server {
rewrite old-url-1 new-url-1 permanent;
rewrite old-url-2 new-url-2 permanent;
rewrite old-url-3 new-url-3 permanent;
#....
rewrite $old-url-1000 $new-url-1000 permanent;
}


Map Style:
============

map $request_uri $new_uri {
default $request_uri;
old-url-1 new-url-1;
old-url-2 new-url-2;
old-url-3 new-url-3;
#....
old-url-1000 new-url-1000;
}

#and something like
server {
try_files $new_uri =404;
}

Since nginx is very fast, I am not able to notice any delay for around 20 rewrites. :|

Is one of above 2 method is recommended for large number of rewrites?

I am inclined towards map, as rewrite adds plenty of notices logs. It's like every rewrite is checked for incoming requests unless it is surrounded by location.

Please let me know if more details are needed.

Thanks.
