Dan makes a good point. Start by comparing the throughput of the two 
methods. You can calculate this by dividing the count of some significant 
timer(s)  by total test runtime. If you don't have a timer or set of timers 
that would allow a direct comparison of throughput under LR and OpenSTA, 
then just count the number of script iterations completed by all users 
divided by the elapsed time of the test. If throughput is roughly the same 
then I'd check to be sure that you haven't inadvertently left some 
connections open (i.e. you might no longer be executing disconnect commands 
because of the loop control logic you have added to the script. )

If it is script pacing that is the culprit, it may be due to something 
simple like needing to tweak wait times so the two scripts are more 
equivalent. You may also need to look at manually inserting synchronize 
commands to make OpenSTA playback more realistic.
