If a particular component, or the system in general, is running
slowly, complete the following steps:
Check whether tracing is on. This could be WebSphere Message Broker user
tracing or service tracing, ODBC tracing, WebSphere MQ tracing,
or native database tracing. If it is, turn the tracing off.
Clear out any old abend files from your errors directory. If you do not clear the directory of unwanted files, you might find
that your system performance degrades due to significant space being used
up.
On Windows, use the workpath -w parameter of the mqsicreatebroker command
to create the errors directory in a hard drive partition that does not contain WebSphere Message Broker or Windows.
