Re: Performance and Memory issues with Windows 11

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

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!
Harald
