Hi Daniele,

Have you submitted a request for the files in cmsdist? (https://github.com/cms-sw/cmsdist/issues)
This is the channel to get the files to show up in the data external package containing these files.

since a change of PSet is required, one can take the opportunity to add the TRKBuilderName as PSet
and remove the hardcoded version at

(different for RECO and HLT)

Just reposting the link for performance (from #3678) : A bit more efficiency for the same fake rate:

for #3690 af7dfbc

tested in CMSSW_7_1_X_2014-05-12-0200 (test area sign370).
There are more tracker-driven electrons (dijet QCD wf 38.0 has ~+20% tracker driven, increasing the total electrons by 10%)

pf candidates content didn't change much.

trackerDrivenElectronSeeds time up by 15 ms/evt in ttbar events (Run-1 MC, wf 202.0), this is about 0.2% of CPU. Most likely it's the 9 different weight files

This pull request is fully signed and it will be integrated in one of the next CMSSW_7_1_X IBs unless changes (tests are also fine). @nclopezo, @ktf can you please take care of it?
