For an unknown reason merging CalTuple.root files is a factor 25 slower than it used to be. Using 'hadd' is a workaround. From Heather:
"My understanding is that hadd just chains the input files and does a
TChain::Merge to create the output file...looking at the code. .it is a
little more intelligent in that..it specifies to the TChain::Merge an
option to "keep" all the TFiles open so it doesn't waste time deleting them. But even more
importantly..it includes "fast" in the option string.. which means:
//If 'option' contains the word 'fast' the merge will be done without
//unzipping or unstreaming the baskets (i.e. direct copy of the raw byte
on disk)."
Warren verified that hadd also works rapidly for merit.root files.
And he verified that using 'pruneTuple' for recon.root files still is quick.
Verified by Anders et al.
