> In terms of reducing the load on IOCs due to search requests, it has been 
> observed that when a typical BURT job of a few thousand channels is run using
> the old BURT, a drop in available CPU power of 5-8% can be clearly observered
> on all IOCs, while no noticeable drop is visible when the same BURT job is run 
> using the new BURT (Note however, this on IOCs that do not have the channels 
> in the BURT job.  Needless to say after locating the channels, the ca_get() 
> operations are still executed on the appropriate IOC..) To view a StripTool 
> plot of the load on 4 sample IOCs at TJNAF when such a test was run, visit:
