CIEMAT

Nice performances in all the tests

DESY

Not good CPU efficiency performances, despite the good usertime (no CPU related). Not negligible load, both from analysis and production activities... can be this the reason? This could explain tails in reading time.

KNU

Despite of a UserTime generally worse than the other sites, reading performances (and so CPU efficiency) very challenging. This could be due to the fact that the site was quite unloaded.

Pisa

CPU performances are not very good. Read time seems to have big values. Question: why dcap-read-msecs is different from tstorage-read-msecs?

Pisa is using an afs shared CMSSW/LCG distribution, sometimes this triggers an 8001 CMSSW error, due to:

---- PluginLibraryLoadError BEGIN
unable to load /afs/pi.infn.it/grid_exp_sw/cms/slc4_ia32_gcc345/cms/cmssw/CMSSW_3_1_4/lib/slc4_ia32_gcc345/pluginCSCGeometryESModule.so 
because libGeometryCommonTopologies.so: cannot open shared object file: No such file or directory
---- PluginLibraryLoadError END

Is this heavy load for Pisa?

Rome

Slightly worse reading performances wrt other dCache sites as KNU, CIEMAT

UCSD

Using a POSIX parallel filesystem, it performs very well in reading.
