Hi,

this works not as intended! If you start the vnstatd before creating the 
ramdisk it
creates filehandles to the files on the disk so the ramdisk is not used 
at all.
How large is the database and how have you created the traffic for the 
test?
All readed files are put to the cache so it might be normal that the 
cache is fuller
after ramdisk mount and copying.
