SDFat is sooo sloooow !!! How to speed-up?

sorry bothering again performances...
i'm trying create set of directories following command :

code: [select]


  strlcpy (my_name,"/blck/9/2/4/1/2/1/6/5/7/9/8/0/2/6/5/8/1/3",name_max_size);
  sd.mkdir(my_name);


guess what, execution of previous 2 lines of code takes 8.45 seconds (!!!) on arduino mega running @ 16 mhz...
i have initialized sdfat :

code: [select]

sd.begin(pin_sdcard_ssn,spi_full_speed)

is there way speed-up directory creation?
many thanks!

are using sdfat.h?  or sd.h?
