Slowing down the system by a certain program?

Question

Iron

Tell me, please, if there are such programs that determine how much it loads and slows down the system, a certain program? For example: we run the test - the program gives out a system score of 94.3%, after installing the antivirus and a second test - the system score is already 91.2%. Does something like this even exist?

Answer 1

Process Explorer

Answer 2

Are there any programs that determine how much it loads and slows down the system, a certain program?

Yes , this program is called Task Manager , and is invoked by pressingCtrl-Alt-Del

the program gives the system rating number

What is a system score?

Answer 3

Tell me, please, if there are such programs that determine how much it loads and slows down the system, a certain program? For example: we run the test - the program gives out a system score of 94.3%, after installing the antivirus and a second test - the system score is already 91.2%.

Do you understand that it is not "programs" that load the system, but specific processes, and they can be either part of a separate program or have nothing to do with it?
For example, you installed an antivirus first. We measured the load on the system, and ... for example, the load became + 10% (conditionally). And then you installed a program that constantly downloads something from the Internet, the antivirus in this case intensively scans all traffic, taking up more and more percent of processor time, memory, and so on. What program in this case will give the load, in fact? The antivirus that formally creates it, or the program that makes the antivirus work in enhanced mode?
Another example is Chrome, at "idle" speeds it usually consumes 300-400 MB of memory, but once you open half a dozen tabs there, suddenly the memory consumption can easily exceed 1 GB, and if you open "heavy" sites in these tabs, then the load on the processor can jump sharply, and if you also continuously download something, then the load on the hard drive will immediately make itself felt.
In other words, it is possible to calculate the "load from the program" only very, very conditionally, and not even "approximately".
PS And if you want to see how much a process is consuming system resources at the moment, there is the usual "Task Manager" for this.

Answer 4

The built-in resource monitor will show who is loading the computer.
You can also use the utilities from the SysInternals suite

Answer 5

If I understood correctly, then you need something like a profiler, but such utilities are usually used by programmers to evaluate the effectiveness of the code.
If you just watch the download, then the task manager is enough for the eyes. Especially since Win8/10 has a "heat map" by columns. The redder the cell, the greater the percentage of the maximum value of the specified resource eaten by the task.

Answer 6

The university in education and work does not solve anything at all. Including any foreign one, except maybe MIT.
No base or anything else. Of course, we are not talking about some shabby corrupt private university, but any regional technical university with a basic IT direction will do, where you will be bang on normally. And believe me, at a university it is better to study what they give there, incl. outdated things. And you will be engaged in self-education in the first two years of work and you will have to do it all your life. Because university material is then more difficult to catch up and understand if nothing is done there. But it's also not critical. Stanford's online video courses also more than cover many important gaps that may not exist at a university.
Everything decides:
1. The desire to learn: prepare for lectures and pairs, read a lot, do all the assignments.
2. The ability to absorb and force oneself to absorb something new, often very incomprehensible
3. Interest, which often manifests itself in the course to the 4th. But everyone jumps off the course on the 2nd. This is manifested in t.ch. and in self-education and in watching courses and in using the knowledge gained and in reading forums.
It's cool if at least one or two teachers at the university are practitioners and even better if they are your supervisors, but this is not critical. Because all the same, you just need to be interested in yourself and read for yourself. This is how the process is set up. And what they teach us poorly is said by those who have not yet left the school and want to be explained something to him, and he decides: to understand this or tomorrow they will explain it again.
Little math is needed. Everything has already been decided. In the case of microcontrollers, there is generally one circuitry and very specific programming in C or less often in Assembler. C++ is not even close. C++ is only about games, operating systems and high-load projects. A very specific area with a high entry threshold.
Here, my colleague and I work in the same company, I get more of it, he is older than me, a manager and used to be a tester, and I am a developer. He graduated from Moscow Institute of Physics and Technology, I graduated from SevNTU. All he could do is just throw a show off, as he studied at the Moscow Institute of Physics and Technology, but he is smart enough not to do that.
Maybe for economists and acquaintances are important, in IT - no. Programmers are not managers, if you recruit only relatives, then you can easily go broke, therefore, only through knowledge and honest interviews.
Programmer himself, 6 years of experience, successful interviews in European companies. It is more profitable to live and work for foreigners here (if you get it in dollars), I graduated from the specialty in microcontrollers and networks, but I work with the web.

Answer 7

One does not replace the other.
Self-education is enough to get a job, but I, personally, regret that I did not enter the same Baumanka in due time.
Many "basic" (read fundamental) things now have to be disassembled and pulled out on their own.
If you want pluses and hardware - I would not advise you to refuse a "strong" university. Naturally, it is possible without it, but, in my opinion, it will be harder.
I won’t say for specific ones, and even here they have already unsubscribed enough.

Answer 8

Look towards the faculty of PM-PU SPbSU - specialty Information Technology. - there you can study and spend enough time on self-education. You will get a good base, but you will have to pester the teachers to explain it better if you want more.
If you want a strong base - Mat-Mekh of the same St. Petersburg State University, only here you have to study a lot. I would even say - zadrotit if you do not learn new material well.
I only know about MSK that the situation at VMK is more than similar to the situation with PM-PU, and Meh-mat is very similar to Mat-Mech :)

Answer 9

A cool university gives more opportunities, more acquaintances, it is easier to get a job in a cool company.

Answer 10

My advice, go to the university is not cool, so that he doesn’t scold you, but learn the software yourself for a technical specialty, sign up for courses, etc.
they don’t teach at universities

Answer 11

The university is not very well-known throughout Russia, but many people know it in their circles - ITMO University
is considered a good base for a programmer, there are opportunities to get education both at low-level programming - microcontrollers, FPGAs, and at a high level, the
main thing is to choose the right department and specialty
In general, even better choose what you like
it's still cool to do what you like

Answer 12

You can enter MATI in the direction of applied mathematics or in the direction of fundamental computer science and information technology.
Non-core items are minimized.
Philosophy, history, foreign language and physical education are required in all universities.
During the training at the institute, a large number of programming languages ​​are studied: pascal, C, C #, C ++, Java, Python, they also teach working with databases and there is a course on cryptography. Also, starting from the 1st course, they teach programming under Unix.
