Lately my tasks go over the time allotted for their completion while other people have no errors.
Is my 10 years old system outdated.\\rwp

I do not see any tasks that did not make deadline. The deadline is two weeks. Your host only has a handful of tasks so you are not overcommitting the host and you return work sent in a day well within the deadline.

Your host is not slow at all even though it may be ten years old.

Continue on as you were. I see nothing wrong.

Continue, but change to Linux - times will drop twice (or more).

My windows times is about 4 times longer than my linux times, how come the windows app is so slow?

When running Milkyway and WCG the runtime in about the same.

How are you using the Win machine

(For example: I have an Android, I keep it to one core for tasks [out of 2Little/2 BIg, four total big.LITTLE], 2 GB memory, but if I play a certain game, [Shop Titans] it does affect at least the Manager, and I imagine it affects run times.)

Also, there are most likely differences between OS's and the BH2 apps....

Has to do with OS support infrastructure. In the case of Universe we noticed when the app sped up was the transition from Ubuntu 18.04 to Ubuntu 20.04. Because I was on the HWE kernels on 18.04, I was running the app on the same kernel version when I transitioned to 20.04 which matched the same kernel version I had been running on 18.04 HWE.

So that being the same, the only other big difference was the transition from libc libraries 2.27 to libc libraries 2.31. We deduced the major speedup was from the improvement in the underlying libc library. Better use of the cpu, better or faster code calls, whatever it was it was the main reason why Linux suddenly became much faster than the same app versions under Windows.

Before that, the tasks pretty much ran about the same speed of maybe 10% faster on Linux compared to the same task on Windows.

So blame Microsoft for not improving their underlying infrastructure compared to Linux. I don't think it has anything to do with the actual application compiles. Just as it now stands, Windows is very much slower than current Linux distros.

Just to clear up any confusion from my last post. The application build was the same for both Windows and Linux. Even for the previous 0.19 version that was in use back two years ago. Now the same for application 0.20 built this past February. I suspect the build configuration for the app is the same for all OS' Just the target is changed for each build.

And I should have labeled the C library correctly as the glibc library or the C library for Gnu based distros.

The C library is responsible for all the "system calls" that define and are used for basic utilities in an OS.

For some reason, the "system calls" in Windows is much slower than in Linux. More overhead I suspect or some such reason.

In fact, the Windows and Linux app uses exactly same source code.
The only difference is compilation environment (gcc vs VS) and using "isnan" and "isinf" replacement for Microsoft functions (as MS don't cover standard C implementation).

Thanks for that clarification, Krzysztof. Always wondered exactly what the differences were between the two OS' as far as the compilation environment.

Is Universe@Home still active? Or should I delete it & make room for active projects?

I'd post screenshots of this project as listed on the BOINC Project Manager installed on my machine, & of my Tasks on this website, if I knew how.

A picture is worth a thousand words.

Yep, plenty of work coming through, although the current batch is almost finished.
Your system hasn't made contact with the project since 26 Nov 2021.

Have you Suspended the Project? Have you set it to No new Tasks?

Problem is she is still using OLD VERSION OF BOINC 7.16.5. that has expired Security Certificate issue.

She needs to download and install latest version of BOINC 7.16.20 Windows 64-bit with VirtualBox

There is no need to install VirtualBox unless you run a project that requires it.
So BOINC without VirtualBox is all that is needed.

I am preparing for "the test" of SSDs, otherwise known as the Pentathlon? I also upgraded my offline storage, increasing by 1 day in preparation for the delays, if any.
We'll see if it helps or hurts. I'll be sure to have some Advil ready just in case. ;^)

Correct. I was linking to what the user already has installed/using per the computers existing profile page.
