* Localize out into separate persistent objects attributes

E.g. when you have a counter, put into its own

The session variable timeout is currently several hours as requird
by our

Making the resolution higher has been observed to reduce conflicts

Thank Chris, good pointsB.
The session variable timeout is currently several hours as requird by our
application. The timeout resolution remains at its default value. I have
not dorked with disabling the inband housekeeping. I don't see how it
would impact on our problem. Am I missing somethi
Changing the architecture will likely get you the most bang but note
also that there are a few knobs that you can turn on the transient
object container UI that may limit the number of conflicts (in the
temp_folder/session_data_container):
- "Data object timeout value" -- the timeout value

Try to partition your collision space. Do you mount a shared temp_folder?
Don't! Do as Chris said and keep a temp_folder per ZEO client. Let the
load balancer send people to the same ZEO client every time (according to
the cookie).
Note that there is no solution for bad coding practice other
than
Peter,
That's pretty much what we've done, but it is not really enough in
our case. Our sites are interactive with lots of per user state. We make
fairly heavy use of session variables to track the state. Our number of
simultaneous users is also fairly high. In addition, during development,

I don't know of any documentation but (correct me if I'm wrong) but
- install zope 2.8.0 or something higher that uses zodb 3.4
- use zeo's and load balancers so that certain requests don't clog your pipes
