| |
As far as I know, if an application modifies a file on an ext3 file ssytem, it actually change the page cache, and the dirty pages will be flushed to disk by kupdate periodically.
My question is: if a file is to be closed, but some of its data pages are marked as dirty, will system block on close() and wait for dirty pages being flushed to disk? If so, it seems to decrease performance significantly if a lot of updates on many small files are involved.
Can someone point me to the right place to check how it works? Thanks!
