Greetings,
I have a servlet that when a request arrives, it makes a profile using
the header "User-Agent" (which contains the type of the client). But,
this process was taking too long and I thought it was my
ProfileFinder.getProfile() method! But, when I made some logs (I put it
below with the source), I saw that the time is "wasted" in the process
of retrieving of session object from request!!!
How can it be?? 20 seconds to get (create) a session object?? The first
time I create a session object it takes 20 seconds!!
I really, really appreciate any help on this....
My system:
-linux redhat 6.2 (kernel 2.2.18)
-tomcat3.2.1
-jdk1.3.0
-PII400 with 256MB
thanks,
Pedro Salazar (my stuff is below)
---------------SOURCE------------------------
long t0=System.currentTimeMillis();
HttpSession sesssion=req.getSession(true);
long t1=System.currentTimeMillis();
getServletContext()log("time:"+(t1-t0) );
Profile p=(Profile)session.getAttribute("profile");
long t2=System.currentTimeMillis();
getServletContext().log("time:"+(t2-t1) );
if(p==null){
String value = req.getHeader("User-Agent");
long t3=System.currentTimeMillis();
getServletContext().log("time:"+(t3-t2) );
p=new Profile(ProfileFinder.getProfile(value));
long t4=System.currentTimeMillis();
getServletContext().log("time:"+(t4-t3) );
session.setAttribute("profile",p);
}
