<p style="-qt-paragraph-type:empty; margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px; -qt-user-state:0;"><br></p>Thanks for response. Problem with another log file is that solution is doubling number of I/O transactions. At some point, data needs to be phrased into database and written to disk. I'm afraid doubling operations will cause bottlenecks during high load traffic peaks and slow-down maximal throughput.<br>

Any known approaches?<br>
