RDD.count() take a lot of time

[Valentin Michajlenko]

Hi!
I load data from list( sc.parallelize() ) with length about 1400000
items. After that I run data.filter(func1).map(func2). This operation
runs less, then a second. But after that function count() (or
collect() ) takes about 30 seconds. Please, help me to reduce this
time!
Best Regards,
Valentin
