Summary

0003301: persistent shutdown performance issues

Description

(rep by Kaith Paulson)

We run two sites; sites are balanced via DNS, and each site is balanced via cisco HW. We do have sticky enabled, but the DNS component makes it impossible to guarantee; our session-config is:

                              <enable-url-rewriting>false</enable-url-rewriting>
                              <save-mode>before-headers</save-mode>
                              <use-persistent-store>true</use-persistent-store>
                              <always-load-session>true</always-load-session>
                              <always-save-session>true</always-save-session>

with the store defined as

              <resin:if test="${resin.isProfessional()}">
                      <persistent-store type="jdbc">
                              <init>
                                      <data-source>jdbc/fooDataSource</data-source>
                                      <table-name>foo/PERSI001</table-name>
                                      <max-idle-time>24h</max-idle-time>
                              </init>
                      </persistent-store>
              </resin:if>

We have seen this in particular on shutdown; in the ugly cases we truncated the tables before startup so no startup issues would have been seen.

We do suspect it is the delete/cleanup JDBC call; right now we have 28 servers sharing one persistent table, and 12 each on another.
