                 According the Guinness Book of World Records, the fastest growing plant is a species of bamboo, which grows at a rate of up to 91cm a day. The fastest growing economy in the world is currently Ethiopia, with a projected growth in GDP of over 8% this year. And although the record for fastest growing Perl team might not be recorded in the Guinness Book of records, our client is a strong contender.
