title: Websphere Shared Log Writer(com.ibm.ejs.ras.SharedLogWriter)
body: <p>I am experiencing very low speed on production environment. I am analyzing the system, and the reason I have found is that all the threads in the system are waiting to access "Shared Log Writer" in websphere environment. What can be the possible reason for this.</p>
  
  <p>what is Websphere Shared Log Writer(com.ibm.ejs.ras.SharedLogWriter), does it manage the log written in the websphere. And why it is blocking the application. My application is also using log4j log and most of the log is written in log4j log files, then if there is some error because of writing on disk, then it should be in the log4j process not in Websphere share log writer.</p>
  
  <p>What are the possible reasons for this. Am I using websphere log file too much for the reporting errors. Please provide me your feedback.</p>
