Hi,
just one note: I've looked to the in scan_bitmap() in bitmap.c. There is:
/* When the bitmap is more than 10% free, anyone can allocate.
* When it's less than 10% free, only files that already use the
* bitmap are allowed. Once we pass 80% full, this restriction
* is lifted.
*
* We do this so that files that grow later still have space
* close to
* their original allocation. This improves locality, and
* presumably
* performance as a result.
*
* This is only an allocation policy and does not make up for
* getting a
* bad hint. Decent hinting must be implemented for this to work
* well.
*/
if (TEST_OPTION(skip_busy, s)
&& SB_FREE_BLOCKS(s) > SB_BLOCK_COUNT(s) / 20) {
So the comment suggests we should lift the restriction when we are 80%
full but if you see the condition, it checks wherher we are 95% full! I
guess that is really asking for trouble and could explain the
behaviour...
Mike could you try changing that 20 in the test to 5? IMHO that could
fix your problem.
