I'll confirm that. I recently wrote a script that had to process a lot 
of data, and I added a progress bar as a matter of course. The script 
took 6 seconds to complete. That felt like quite a long time, so I 
started adjusting the progress update to only change every so many 
cycles. The longer between updates, the faster the script ran. Then I 
had an epiphany and removed the progress bar altogether -- and the same 
data got processed in about a dozen milliseconds. The entire lag was the 
progress bar!

Rev is so fast, sometimes you forget.
