  • Performance and Memory issues with Windows 11

    From Harald Oehlmann@21:1/5 to All on Fri Feb 7 14:25:49 2025
    Dear Tcl/Tk group,

    is anybody aware of any issues with Windows 11?

    I updated my laptop from Windows 10 to Windows 11 and all Tcl programs
    feel 10 times slower.
    They are apparently waiting for something I don't know.
    A client reports of an error box "unable to realloc 90500 bytes" which
    apprears after a day of not using the program.

    This is TCL 8.6.16 (or 8.6.13 in the client case) compiled with MS-VC6.
    I know, the move to TCL 9 and a more recent compiler is pending.

    Does anybody has an idea here?

    Thanks for all,
    Harald

    Well, 9.0.1 works under the latest wsl. I had to install a bunch of stuff with apt but,it worked.

    Thanks for all the replies.
    I was still using TCL 8.6.13 32 bit starkits (from Ashok), extensions
    compiled with MS-VC6.
    I am making first steps with TCL/Tk 9 and x64 platform, compiled by VS2022.
    The increased speed is AMAZING !
    It feels like 5 times faster.

    Specially, file write often took a long sleep. This is gone.

    Thanks for all this awesome work!

    I'm using Tcl with Windows 11 on a regular basis and don't see any
    issues compared to Windows 10.
