High consumption of memory and CPU.

[Alessandro]

Good morning.

I am developing an application in uniGUI.

However I came across something scary recently: By placing the application on the server in the cloud, the application was running for a week nonstop some users began during this period to do some tests. The problem came as I went to visit the server via remote connection and came across the application consuming 98% of CPU and memory !!!

It can not exist. Do any of you have any idea about what may be happening or any tips, or perhaps a best practice of how to avoid this extremely wasteful consumption of the server machine?

Grateful.

 

 

Bom dia pessoal.

Estou desenvolvendo uma aplicação em uniGUI. No entanto me deparei com algo assustador recentemente: Ao colocar a aplicação no Servidor, na nuvem, o aplicativo ficou rodando por uma semana Ininterruptamente e alguns usuários começaram neste período a fazer alguns testes. Até aí normal. O problema veio quanto eu fui visitar o servidor via conexão remota e deparei com a aplicação consumindo 98% da CPU e Memória!!! 

Isso não pode existir. Alguém de vocês tem alguma ideia sobre o que pode estar acontecendo ou alguma dica, ou talvez uma melhor prática de como evitar esse consumo extremamente exagerado da máquina servidora?

Grato.

How much ram is 98% of yr server?

Bom dia Alessandro,

 

Quantos Form, Frame e DataModule (UniGui) você possui em sua aplicação?

 

Você utiliza geração de relatórios em sua aplicação, se sim qual ferramenta?

[Farshad Mohajeri]

Is it CPU or RAM?

[Alessandro]

 

Marlon: 4 DM, ~50 forms, nenhum frame, utilizo fastReport para gerar relatórios.

 

[Alessandro]

 

Farshad Mohajeri: my server is virtual machine. 

 

[Farshad Mohajeri]

Farshad Mohajeri: my server is virtual machine. 

 

What are its specs?

[Farshad Mohajeri]

And pls specify uniGUI version and edition.

[Alessandro]

Delphi XE5, Win7, 32bits, 

uniGUI Web Application Framework

Version:0.95.0 build 1046

 

I'm developing with this version, but to launch the system to market, want to buy the final version of uniGUI.

[Marlon Nardi]

Alessandro pesquise em todo seu projeto e verifique se você esta usando a classe frxChart.

[rencarnacion]

I guess that version is so Old You should test with the last version

I have a big application running and until now the behavior is very good, low memory and CPU Consumption

 

You can test your application with the stress test tools

[Alessandro]

 

Marlon, tinha somente um frxChar no mainModule, e foi removido.

 

[Phxtecno]

Hi Ronny,

which stress test tools do you mean ?

[rencarnacion]

When you install Unigui you can find the tools on the following address in you Unigui Installation

 

c:\Program Files (x86)\FMSoft\Framework\uniGUI\Utils\StressTestTool\

[Phxtecno]

Thank you !

I didn't see...

[Alessandro]

I don´t have "Utils\StressTestTool\"...

Where I find it?

[Skepsis IT]

You must download a more recent version that includes it. StressTest added about 3 or 4 latest builds.

 

Furthermore how much ram has your vm?

[Farshad Mohajeri]

Stress Test tool is only available in commercial edition.

[Alessandro]

You must download a more recent version that includes it. StressTest added about 3 or 4 latest builds.

 

Furthermore how much ram has your vm?

 

4Gb

[Skepsis IT]

4Gb

 

It's fair enough.

 

Did you enables memory leaks?

 

ReportMemoryLeaksOnShutdown := True;

 

For finding out if something goes wrong?

Hello PhxTecno

if you have a big data, the best practice is to
- Close DataSet after using them
- Don'nt use FetchAll = True On your Dataset  

- Also very important Set :  UniDBGrid.WebOptions.FetchAll = False;
- Free all Objects you created on Destroy's form event.

Best regards.
