    "abstract": "The BaBar experiment is the particle detector at the PEP-II B-factory\nfacility at the Stanford Linear Accelerator Center. During the summer shutdown\n2002 the BaBar Event Building and Level-3 trigger farm were upgraded from 60\nSun Ultra-5 machines and 100MBit/s Ethernet to 50 Dual-CPU 1.4GHz Pentium-III\nsystems with Gigabit Ethernet. Combined with an upgrade to Gigabit Ethernet on\nthe source side and a major feature extraction software speedup, this pushes\nthe performance of the BaBar event builder and L3 filter to 5.5kHz at current\nbackground levels, almost three times the original design rate of 2kHz. For our\nspecific application the new farm provides 8.5 times the CPU power of the old\nsystem.",
