Before I started debian/alpine via "Win + R" and conhost was used which doesn't support Shift+Insert (although they added Ctrl+Shift+V to paste). I use Shift+Ins a lot in Mintty. And Shift+PgUp/PgDown which is absent in conhost. > - Revamped pseudo console support. Conditionally activating it only when > a non-cygwin application is run. I reread latest mails to see if anyone reported about mintty CPU usage. I read about a new version and updated and problems seems disappeared but I'm not sure about who is responsible: /var/log/setup.log: 2021/04/02 15:56:32 1 install cygwin 3.2.0-1 2021/04/02 15:56:32 2 erase cygwin 3.1.7-1 2021/04/02 15:56:32 15 install mintty 3.4.7-1 2021/04/02 15:56:32 16 erase mintty 3.4.6-1 Basically all mintty processes took about 1-1.5% cpu load. 5 minnty caused 7-10% CPU load (and electrical bills + fan noise) even when terminals were idling. Now each idling mintty takes 0.06-.11% CPU load (reported by procexp). I took stack reports from procexp before updates. There are 2 threads caused CPU load (first took 0.7% CPU, second 0.5% CPU on average) and the picture reproduced 100%: ntoskrnl.exe!KeSynchronizeExecution+0x5b66 ntoskrnl.exe!KeWaitForMutexObject+0x1460 ntoskrnl.exe!KeWaitForMutexObject+0x98f ntoskrnl.exe!KeWaitForMutexObject+0x233 ntoskrnl.exe!ExWaitForRundownProtectionRelease+0x7dd ntoskrnl.exe!KeWaitForMutexObject+0x3a29 ntoskrnl.exe!KeWaitForMutexObject+0x1787 ntoskrnl.exe!KeWaitForMutexObject+0x98f ntoskrnl.exe!KeDelayExecutionThread+0x122 ntoskrnl.exe!SeReleaseSubjectContext+0x21bf ntoskrnl.exe!setjmpex+0x7c15 ntdll.dll!NtDelayExecution+0x14 KERNELBASE.dll!SleepEx+0x9e cygwin1.dll!feinitialise+0x5b43a cygwin1.dll!setprogname+0x3041 cygwin1.dll!setprogname+0x3656 cygwin1.dll!setprogname+0x4126 cygwin1.dll!setprogname+0x41d4 KERNEL32.dll!BaseThreadInitThunk+0x14 ntdll.dll!RtlUserThreadStart+0x21 ntoskrnl.exe!KeSynchronizeExecution+0x5b66 ntoskrnl.exe!KeWaitForMutexObject+0x1460 ntoskrnl.exe!KeWaitForMutexObject+0x98f ntoskrnl.exe!KeWaitForMutexObject+0x233 ntoskrnl.exe!ExWaitForRundownProtectionRelease+0x7dd ntoskrnl.exe!KeWaitForMutexObject+0x3a29 ntoskrnl.exe!KeWaitForMutexObject+0x1787 ntoskrnl.exe!KeWaitForMutexObject+0x98f ntoskrnl.exe!KeWaitForMultipleObjects+0x2be ntoskrnl.exe!ObWaitForMultipleObjects+0x2f0 ntoskrnl.exe!FsRtlCancellableWaitForMultipleObjects+0x229 ntoskrnl.exe!setjmpex+0x7c15 ntdll.dll!NtWaitForMultipleObjects+0x14 KERNELBASE.dll!WaitForMultipleObjectsEx+0xf0 KERNELBASE.dll!WaitForMultipleObjects+0xe cygwin1.dll!setprogname+0x445c cygwin1.dll!acl_get_perm+0x4ee0 cygwin1.dll!setprogname+0x3041 cygwin1.dll!setprogname+0x3656 cygwin1.dll!setprogname+0x4126 cygwin1.dll!setprogname+0x41d4 KERNEL32.dll!BaseThreadInitThunk+0x14 ntdll.dll!RtlUserThreadStart+0x21 With new Cygwin DLL & mintty the picture was changed to a single thread consuming 0.06-0.11% CPU: ntoskrnl.exe!KeSynchronizeExecution+0x5b66 ntoskrnl.exe!KeWaitForMutexObject+0x1460 ntoskrnl.exe!KeWaitForMutexObject+0x98f ntoskrnl.exe!KeWaitForMutexObject+0x233 ntoskrnl.exe!ExWaitForRundownProtectionRelease+0x7dd ntoskrnl.exe!KeWaitForMutexObject+0x3a29 ntoskrnl.exe!KeWaitForMutexObject+0x1787 ntoskrnl.exe!KeWaitForMutexObject+0x98f ntoskrnl.exe!KeWaitForMultipleObjects+0x2be ntoskrnl.exe!ObWaitForMultipleObjects+0x2f0 ntoskrnl.exe!FsRtlCancellableWaitForMultipleObjects+0x229 ntoskrnl.exe!setjmpex+0x7c15 ntdll.dll!NtWaitForMultipleObjects+0x14 KERNELBASE.dll!WaitForMultipleObjectsEx+0xf0 KERNELBASE.dll!WaitForMultipleObjects+0xe cygwin1.dll!_assert+0x460c cygwin1.dll!acl_get_perm+0x52b0 cygwin1.dll!_assert+0x31f1 cygwin1.dll!_assert+0x3806 cygwin1.dll!_assert+0x42d6 cygwin1.dll!_assert+0x4384 KERNEL32.dll!BaseThreadInitThunk+0x14 ntdll.dll!RtlUserThreadStart+0x21 Next time I try to use real profiler for report, have to get familiar with good one. -- http://defun.work/ -- Problem reports: https://cygwin.com/problems.html FAQ: https://cygwin.com/faq/ Documentation: https://cygwin.com/docs.html Unsubscribe info: https://cygwin.com/ml/#unsubscribe-simple
