Hello,

I have a TIdTcpServer project with many clients that have permanent connections.  At the moment I am having 2300 concurrent connections (=2300 threads) all the time and I am running into performance problems.  The machine I am running the server application on is a Windows Server 2019 with 8 cores and 24 GB of RAM.  
I suspect the application starts running slow because of the thread scheduling of the operating system.

I have been reading about the IdSchedulerOfThreadPool that would use a thread pool instead of 1 thread per connection, but I also read something that contradicts that a  IdSchedulerOfThreadPool would help.

What is the best I can do to handle that many concurrent connections?

Hello Intraweb,
is there a way to understand the behavior of TServerController's properties ThreadPoolSize / UseThreadPool?
I was wondering if exists something helpful to allow my applications being scalable among more IIS applications.

Thanks

Hi guys,

Enjoy! 

Hello,

I tried to install IntraWeb 16.1.2 for Delphi XE7, but the provided design-time package dclIntraweb_16_DXE7.bpl cannot be loaded into Delphi XE7.

When checking the dependencies with Dependency Walker, I noticed that this BPL depends on:

rtl220.bpl

vcl220.bpl

designide220.bpl


These are the runtime packages for Delphi XE8 , not XE7.

Because of this mismatch, Delphi XE7 cannot load the package — it always fails with "Cannot find module" error.

It looks like the “XE7” build of IntraWeb 16 was in fact compiled against XE8 runtime. Could you please check and provide the correct build for XE7 (210 runtime packages)?

Thank you. 

Jacek

After upgrading my PC from win 10 to win 11, CGDevtools components was no longer recognized within RadStudio. I attempted to reinstall CGDevTools with the installer we've always used, and I'm getting a "Download failed: Server internal error (500)". I now see that the main CGDevTools website is down, and ATOZED is now supporting CGDevTools. How can I reinstall CGDevTools to fix my dev environment under Rad Studio? I assume whatever the installer is trying to connect to is no longer available. The version I'm using is IWCGJQComps for Intraweb 15.2.32. I've attached a screenshot of the error to this post. Thanks.

Hi,

i moved a valid certificate from a Windows 10 intraweb server to a fresh Windows 11 installation successfully by using the certificate Manager (V1.1.0.4).

However, when i try to add the SSL bindings for port 443 an error message is displayed.

Best Regards
Juergen
