hello,  <br>   I am having performance degradation issues with repeated queries of monetdb. I am attempting to use monetdb for financial tick data and make sql queries requesting all quotes for a symbol on date x where time &gt; y and time &lt;z.  Previously monetdb had worked great for this task and was extremely quick.  However, I had a crash last week of the server it was built on.  After this monetdb ran incredibly slow on the order of 25 times slower than it was running before.  I rebuilt monetdb and it ran quickly for a day or two and started degrading in speed.  Could someone give a hint or two on how I should go about debugging this?  Is there a optimization task that I need to run?  <br>
 <br>I am really at a loss of how I should handle this.  I have been running queries via mclient  -s from my  program written in python.  I previously found the python bindings too slow.  <br><br>Stats:<br>cpu: 2 opteron 2222<br>
