Track and desktop and kernel appear to become unresponsive when copying
large numbers of files from one drive to anther drive. No debug info, just
something I noticed recently as I have been migrating from a 100gb drive
to a 1tb drive. Neither of which are the primary OS drive. No crash, but
certainly the system hangs up and becomes unresponsive. Both drives are
similar in speed in fact the 1tb drive is marginally faster on write then
the the older drive was on read.
This is also noticeable if you copy files from a USB thumb drive to a
separate data disk.It is usually OK if you copy one large file, However
copying lots of small text files say a few thousand, generally makes it
very obvious.
In fact a good test case is to take the Haiku trunk and move it from one
non boot drive to another non boot drive, or to move a copy of the Haiku
trunk from a USB stick to a separate drive. I did a few test cases on
other hardware. single,dual,hex core machines make no difference.
I checked back across a few nightly builds back to r1a3 and the
performance issue is present there as well.
