Strange progress behaviour

[salvatore]

hello all,

FreeFileSync 5.18

I have noticed a strange behaviour during synchronization when the number of objects to synchronize is huge. The counters shown in the progress window sometimes go negative and even if the job is not finished yet the green bar is already at 100%, that's to say that they show a negative number of objects becoming more and more negative, and even a negative remaining time and a full progress bar.

But when the number of objects diminishes, at a certain point the counters become right and so the progress bar.

I'm thinking of possible counters overflow.

Moreover, is there anything to do to enhance compare/synchronization speed? My sync jobs are usually among computers on a gigabit local network, but when the number of objetcs is really big it tooks a considerable amount of time. Computers are of various types: The main computer where the job is started is a dual core 64 bit with Windows 7 and the destination computer is an old Pentium 4 1.7 GB with Windows XP.

Negative numbers can happen if the actual bytes/items transferred is larger than what is expected, however the "expected" will be updated after such a situation occurred, so there may be a short time frame where the numbers look strange.

this behaviour should be corrected showing something else while waiting that the real and "expected" values agree.

This problem has been fixed:
"Prevent temporarily incorrect statistics after unexpected increase in workload"

This means that if the bytes to copy increase after comparison (or even during synchronization), this is handled immediately and FFS won't wait until the end of processing the current item to adapt the statistics.

Here's the new version for testing:
