Hi there,

I wonder if it my response times will decrease if I split a 20Gb datafile into ten 2Gb datafiles (located on a single volume) ? Is there a critical size for a datafile in terms of performance ? (unfortunately we can not use partitionning...)

Thanks for your ideas,

Nope,it shouldnt. Infact if you are using ordinary filesystem ( as opposed to Raw devices or Veritas or Direct I/O),the performance should increase by splitting the 20GB datafile into 10 2GB files due to reduced UFS writer locks.
