I briefly looked over the log, but I didn't see anything that might indicate why Mifos was running slowly.
Questions/comments:
* Looks like there were 5 restarts. Why?
* While Mifos was running slowly, what was going on with memory
and CPU usage on both the application and database servers?
* Any chance the MySQL slow query log was enabled while Mifos was
running slowly?
* Were there any custom queries/reports (external to Mifos) being
executed while Mifos was running slowly?
* The Tomcat "localhost" log may not always contain the most
useful messages. Unfortunately, it is often necessary to examine
all logs. Was there any more useful information in the
application log (Mifos_log.log), the Tomcat "catalina" log, or
the Tomcat console itself?
* I saw a bunch of occurrences of the strings
"PageExpiredException" and "requestDestroyed", I believe these
generally indicate that a HTTP connection died while serving a
request, either due to poor connectivity or because someone hit
the browser's "stop" button. I don't know if broken requests
affect application performance, but I suppose if someone kept
starting an expensive operation (like a big search, collection
sheet entry, or report) *and* clicking "stop" before it
completed, *and* it took Tomcat a while to figure out that the
request didn't need to be served, that might slow down Mifos for
all users.
* NumberFormatException errors may be bugs in Mifos; these types
of errors should be handled by Mifos and a friendly error
message should be displayed in the Web interface. If you or
anyone can reproduce the error on the trunk, please submit a
DEFECT in the issue tracker. I notice that issue 2204 mentions a
NumberFormatException.
