R help - May 2013 - Increasing time of simulation

Hi

 

maybe someone could help

 

Program:

NS=10

ONS=100

. some declarations

############################## f. START
############################################

. functions definitions

##############################  f.  STOP
############################################

 

for (osym in 1:ONS) {

  wnk_sym=array(0,c(49,10,NS))

  for (sym in 1:NS) {

    #### . counting wnk (matrix 49x10) based on the random numbers

    wnk_sym[,,sym]=wnk

  } 

  save(wnk_sym,file=paste(where,file,osym,'.RData',sep=''))

  rm(wnk_sym)

} 

 

The problem is first simulations takes ca 20s each, but time is constantly
increasing, up to 150s. Any idea why?

RAM is not a problem (8GB) on win7 x64
