Re: Coldfusion 8 erratic behavior

2013-05-26 Thread Russ Michaels

a db queries being fast or slow is irrelevant.
What about closed connections, what about slow responses from the database
server, what about network issues between web and database server.
All of these can cause a page to run slow or even hang waiting for a reply
from the server.
If a user closes his browser or goes away form the page before a response
is received, then this can also leave the original request hanging.

Re: Coldfusion 8 erratic behavior

2013-05-26 Thread Dave Watts

 How can I determine what causes a coldfusion 8 page to be fast loading 
 sometimes and other times, extremely slow? The server
 seems to have enough memory and the traffic is not high. The db query part of 
 the page is fast according to Fusion Reactor. I don't
 see any leads in the Fusion Reactor Request Detail.  What else should I 
 check? Thanks in advance. Rick

One thing to check, that no one else has mentioned specifically here,
is what else is running concurrently with that page when it's slow. A
stack trace may show you an indication that this page is waiting for
something else to finish.

Check coldfusion's server monitor -  in the statistics page, look for 
cumulative server usage..I had a similiar problem and it turned 
out to be a denial of service attack against 1 page..  and it did not 
show up on google analytics. Look for a huge amount of traffic.

Like Russ said, check the stack. If you can't seem to catch it, you can
set up FusionReactor to send you notifications (that include the stack
trace) when threads hit a certain time in their life span.

You said you didn't think it was DB. How did you determine that? Does it
mean you are using the FusionReactor JDBC wrapper on the datasource? If
not, then I suggest doing that so you can get a full picture of what's
going on with the DB actions in your request.

when it is being slow, do a stack trace and it should give you an idea what
is causing it.
usually it is a db query.
