    Too slow while comparing folder/text file

    I am using the latest version of BC4 in OSX, High Sierra.
    Recently, I am suffering from a speed issue about BC4.
    I do not know that the problem occurs from the latest version of BC4 or High Sierra.
    Please check this problem.

    I use...
    OSX High Sierra 10.13.1
    BC4 Version 4.2.3 (build 22587)
    Mac Pro (Late 2013)
    3.7 GHz Quad-Core Intel Xeon E5
    64 GB 1866 MHz DDR3
    1TB SSD

    Thanks

    First, back up your settings using the Tools menu -> Export wizard and export everything as a BCSettings.bcpkg. Then try Tools menu -> Restore to Factory Defaults. Fully reboot your machine, and then restart BC4 with a simple text comparison by loading BC4 first, loading a blank text compare, and then loading a pair of plain .txt files into the compare. How does this behave? We can then re-work in your previous workflow or settings a few at a time to try and find the offending culprit.

    I've tried disconnecting all external monitors and resetting the built-in retina display to its default resolution. After doing that I also tried quitting a restarting BC4. Nothing helped.

    Thanks for the report. We have had a couple in this thread, but haven't narrowed down the exact causes yet. What hardware configuration are you running? What resolution are you running at; if you decrease it do you see a performance increase?

    and inline editing of text files is not excruciatingly slow. I'm running BC4 Version 4.2.4 (build 22795) on macOS Sierra 10.12.6 (16G1314)

    I find window scrolling to be painfully slow (especially in text comparison windows.) I've been using Beyond Compare on the Mac since it came out (and on Windows for years before that) and only recently came to feel that scrolling is no longer a zippy as it used to be.

    Sadly, I can confirm the issue. BC4 is deadly slow (unusable) in the window comparing folders trees.

    As other users, I have a multimonitors (4) with 4K:
    - internal MBP TB 15 2016
    - 1 4K
    - 1 FHD
    - 1 HD

    Not sure, but it looks like this is related to 4.2.4.

    The issue is mainly when using BC4 on the external 4k display, when moving the window on the MBP screen. Things are getting better.

    How can I revert back to 4.2.3 ?

    Thanks,

    We've now tested with two systems, using a 4K and a 1080p display, on High Sierra and Mountain Lion, and the performance looks fine. It's a little more sluggish than I'd like, but that's not new, and it doesn't appear to have gotten worse recently. Part of it is that macOS isn't the lead platform, so there are some inefficiencies compared to the Windows version or a macOS-only app, and part of it is that we're using some outdated technologies. We're working on replacing those, but it's a big project and it's going to take significant time to complete.

    Were you using BC previously on the same computer without the slowdown?

    We are interested in hearing from anyone who's experiencing this to see how widespread it is. One person sent us a YouTube video showing the problem, and any sort of screen captured video like that would be very useful.

    callion82,

    You said your Mac Pro 2013 has a 4K and 1080p monitor (vertical). Is the performance issue better if you move BC's window to the 1080p monitor instead of the 4K monitor, or do both displays have equally bad performance for BC?

    We received a 4K monitor for testing, but haven't been able to duplicate the issue so far. Our Mac developer is running 10.11 on his primary system due to limitations of a development tool he uses. It's possible the performance issue only happens in 10.12 and 10.13 so we'll have to do further testing.

    Our Mac developer uses dual 1600x1200 monitors, that might be why he hasn't encountered the performance issue you reported. I ordered a 4K monitor for Mac performance testing in our office today, we'll follow up in this forum thread after we've run some tests with it.

    Thanks for the additional information. Our Mac developer is out on vacation, when he's back in the office I'll discuss this issue with him and post a follow up.

    Apple's Support Communities topic for High Sierra has multiple posts about slowdowns after upgrading to High Sierra:

    Q: macOS High Sierra 10.13 slow graphics after battery sleep

    Q: High Sierra has made my MacBook Pro abysmally slow
    No, only BC4.

    I read all contents you wrote. However, I do not think they are related to this issue.

    The worst thing I suffer is the movement of cursor in text/folder comparison.

    I usually use BC4 by keystroke while file/folder comparing. The movement is following too slowly...
