I have  set up a single node hadoop  and running my cascalog queries on it 
. 
Good and i get results too . Now  i am using clojure.core/time  to evaluate 
how much time cascalog queries took for execution.
Very Strange thing is: each time i run the cascalog query , i get different 
elapsed time for same query .
For example (what i tried) :

(time  






*(?<- (stdout)         [?timestamp ?assembly ?category ]        (info-tap 
:> ?timestamp ?assembly ?category )       (clojure.string/trim ?category :> 
?trimmed-category)       (= ?trimmed-category "Start Inhibit")) )when i run 
1st time :  Elapsed time: 610.221708 msecswhen i run 2nd time : Elapsed 
time :787.81836 msecswhen i run 3rd time : Elapsed time : 680.919887 
msecsPlease  let me know whats wrong ?. I Need to make Performance tests on 
cascalog queries , this should be accurate .Hoping to get help from someone 
.Thank you ,- Sindhu.*
