Hi,
I use meld for big tree comparison (ArcitcFox - Firefox) and have often
found issues and asked for help.
I can compare the same operation with Meld on Linux or FreeBSD and it is
usable on comparable powered CPUs and systems! Maybe it takes longer to
scan the tree, but then opening a file takes e.g. a one to a couple of
seconds, there is a spinner, then it ends.
On Mac, sometimes meld crashes, sometimes stops opening file after while
of working, but can be quit and reopened
Old MacOS 10.5-10.9 do not work, no windows opens (10.7 used to work,
broke) so I cannot use these as comparisons
Beyond these issues which are specific to MacOS, I also have a "strange"
performance issue Opening a file comparison from the tree can be very
slow, it may take many minutes. The file opens, but then "comparing"
remains in progress for a long time, including spinner.. then it seems
to mostly show, spinner continues. Sometimes finishes, sometimes "spins
forever" until I loose patience: left it for hours!
MacBook Pro 15" Core Duo with 10.11: acceptably usable, best of all my
systems
MacBook Pro 13" Core Duo with 10.13: unusable: comparison sometimes
never complete, even after 1h or so
MacBook Pro 15" Core i7 with 10.13: quite slow, but with a lot of
patience somehow usable
MacBook Air Core i5 with 10.15: slow, but usable with patience
Interestingly, it is not directly related to the number of differences
or to show or to the lenght of file!
The systems are about the same level of MacPorts and the issue is
happening since weeks/months. I just recently noticed that the older
system with 10.11 is faster. I was not understanding why the 13" was so
slow, the CPUs are comparable. I upgraded RAM so they match.
At a first glance it seems that newer OS introduces some issue!
Someone with different systems willing to reproduce, help fix it, ecc?
I was wondering if it makes sense to test GTK on X11 and if I can do
that while maintaining Aqua or if to do the test I need to remove all
Aqua GTK applications, switch and then get back. Theoretically it could
help narrowing down to a potential drawing issue or if it has python &
threading issue.
