Hi,
Im struggling with a couple of high response times when using
varnish on our site. I have configured varnish so it will
cache only static content (jpg,gif,png,css,js etc) even if a
cookie is set. But all our jpeg's are getting a high response
time when Im running some test against the site.
One of the jpeg's are pic_mini.jpg, it has a response time of 357ms. I turned on logging and vcl_trace and found the line:

14 Debug c "Hash Match:
/Portals/0/Picture/pic_mini.jpg#www3.mydomain.com#"
14 Debug c "on waiting list on obj 1767384108"

Does "on waiting list" has something to do with the high response time?

The rest fo the log for pic_mini.jpg is:

In vcl_recv im fetching static content using:

sub vcl_recv {

# *.jpg , *.jpeg , *.gif , *.png , *.ico
if (req.url ~ ".(jpg|gif|png|jpeg|ico)$") {
lookup;
}

# *.js , *.css , *.swf
if (req.url ~ ".(js|css|swf)$") {
lookup;
}

if (req.http.Cookie) {

# *.jpg , *.jpeg , *.gif , *.png , *.ico
if (req.url ~ ".(jpg|gif|png|jpeg|ico)$") {
lookup;
}

# *.js , *.css , *.swf
if (req.url ~ ".(js|css|swf)$") {
lookup;
}
}

pass;
} #RECV


and my vcl_fetch is using:
sub vcl_fetch {

# *.jpg , *.jpeg , *.gif , *.png , *.ico
if (req.url ~ ".(jpg|gif|png|jpeg|ico)$") {
insert;
}

# *.js , *.css , *.swf
if (req.url ~ ".(js|css|swf)$") {
insert;
}

if (obj.http.Set-Cookie) {
# *.jpg , *.jpeg , *.gif , *.png , *.ico
if (req.url ~ ".(jpg|gif|png|jpeg|ico)$") {
insert;
}

# *.js , *.css , *.swf
if (req.url ~ ".(js|css|swf)$") {
insert;
}

pass;
}

#
pass;

} #FETCH
