v5.11 appears to still have the high CPU / slow file transfer bug

Posts: 3 · vbjhfdbdj 12 Jan 2013, 22:50

I am using FFS v5.11 to transfer 500GB (150,000 files) between two external USB 2.0 hard drives.

The transfer starts off fine in the 8-15 MB/s range then over the period of an hour or two CPU rises to 50% on my i7 and bandwidth drops to a crawl of a few bytes/s.

I have uninstalled the old version and have installed v5.11 ... turned off everything ... virus scanners, etc ... restarted many times ... and still it ends up crawling.

Any suggestions ?

Cheers,
Mike.

Some more information ....

Using compare file time and size the system works normal.

Using compare file contents also causes the very slow / high CPU bug.

I am using Mirror Sync which causes the bug (I have not tried other types of syncing).

Everything else is at the default settings.

Cheers,
Mike.

The bug as reported here
viewtopic.php?t=1097
is definitively solved. So what you are seeing must have some other explanation. I assume you are on a dual-core CPU and FFS is consuming 100% of one of the cores? Does this problem also occur on any of the older FFS versions, except for v5.10?

Crap !

I just rechecked the version (it was v5.10) ... I must have reinstalled the wrong one.

I have installed v5.11 now and it is working fine for the last 2 hours.

My mistake ... FFS is an excellent piece of software ...

Feel free to delete this whole thread if you can.
