If disc cache is less than file size - delay write will not optimize wrights as expected.
I use old ReGetPro for downloading files (it does not have internal write buffer).
When I download 400mbyte file- it's ok, but if file sive is >1GByte it overloads disk by write operatons.
P.S. i have set 1GB cache for my system drive which is also drive for downloads. my download speed limit may vary from 16Mbytes/sec to 24MBytes/sec(yes, MBytes, not MBits(2x100mbit connections)).

Hi PtDragon,

When there is no space to hold deferred wrtie data, program will issue an urgent write to make room for the new write data. You may try to reduce the delay time, thus reduces the urgent writes.

That didn't help at all (delay was 512sec, reduced to 5sec).
I expected nearby sectors to be written together(that will give large performance boost)...
Other download managers which have own cache perform much faster on write(but not on download)...
I can't use more RAM for cache(i got only 8Gb ram and lots of memory-hog software to work with) ...
Can you check write functions optimization?
P.S. my system drive is WD 10K RPM (WDC WD1500HLFS) which is capable of writing at least 40mbytes/sec and at most up to 70mbytes/sec...
