[twsocket] twsocket cpu usage
Hello Is there a way to limit the cpu usage when receiving files thru TWsocket? Usualy CPU is 90-100% used and the computer freezes for the time the transfer is made. Radu ___ No banners. No pop-ups.

Hello, I think you have a problem because it should not eat 100% CPU nor freeze your system. regards. imc Hello imc Is there a way to limit the cpu usage when receiving files thru TWsocket? imc Usualy CPU is 90-100% used and the computer freezes for the time the transfer is made. imc Radu imc ___ imc No banners.

TWSocket component doesn't use much of the CPU. It is likely that in your application you've done some wait loop which eat all CPU. Can you show the part of your code which receive a file ? -- Contribute to the SSL Effort.

Re: [twsocket] twsocket cpu usage
Hello Radu, It is also possible if you send / receive very mutch data at high speed and save to disk or so. This take some time and meanwhile next chunck is probably already received. If this is the reason then you can slow down the sending a little by waiting a littel between data chuncks. You can do this using a timer for example. --- Rgds, Wilfried [TeamICS] http://www.overbyte.be/eng/overbyte/teamics.html http://www.mestdagh.biz Thursday, March 16, 2006, 13:50, [EMAIL PROTECTED] wrote: Hello Is there a way to limit the cpu usage when receiving files thru TWsocket?

Re: [twsocket] twsocket cpu usage
I think he is using sync methods which consume a fake 100% CPU. I experienced the same with TFtpServer 5 years ago before I switched to async. the reason is the default message pump of ICS uses PeekMessage whereas my suggestion is to build a message pump with GetMessage.

Re: [twsocket] twsocket cpu usage
Indeed the data transfered is continously transfered at high speed and it is written directly to disk. Which is the best method I could use to slow cpu usage? - make a timer and send data whith interrupts (but how to make a timer whith 0.2 seconds step for example?) - find somehow a component that limits bandwidth so that data to be forced to be send in slower motion - other method Radu --- On Thu 03/16, Wilfried Mestdagh [EMAIL PROTECTED] wrote: From: Wilfried Mestdagh [mailto: [EMAIL PROTECTED] To: twsocket@elists.org Date: Thu, 16 Mar 2006 14:55:13 +0100 Subject: Re: [twsocket] twsocket cpu usage Hello Radu,It is also possible if you send / receive very mutch data at high speedand save to disk or so.

Re: [twsocket] twsocket cpu usage
Or throttle the sending of the data in the sender application. Now you have probably something like this: Socket.Send(DataChunck, Len); in SocketDataSent: SendNext; in SendNext: // read next chunck from file Socket.Send(DataChunck, Len); == you can change thsi as follow == Socket.Send(DataChunck, Len); in SocketDataSent: with TTimer.Create(Self) do begin interval := 200; enabled := True; OnTimer := SendNextChunckTimerTimer; end; in SendNextChunckTimerTimer: Sender.Free; SendNext; --- Rgds, Wilfried [TeamICS] http://www.overbyte.be/eng/overbyte/teamics.html http://www.mestdagh.biz Thursday, March 16, 2006, 15:15, Guillaume MAISON wrote: Indeed the data transfered is continously transfered at high speed and it is written directly to disk.

Re: [twsocket] twsocket cpu usage
Hello! Is there a way to limit the cpu usage when receiving files thru TWsocket? Usualy CPU is 90-100% used and the computer freezes for the time the transfer is made. If you write in a random sized chunks (especially byte-per-write), use some kind of write-buffering filestream (AFAIR Arno has coded one). If that won't help you much, insert sleep(0); *before* call to write/writefile/blockwrite/etc. Inserting your code into separate thread won't help you if you're experiencing *computer* (not program!) freezes. Also, don't use dynamically-sized memory streams and memory buffers (like dynamic arrays, note that long string is also a kind of dynamic array, and concatenating strings is a kind of dynamic resize of an array), you won't get any benefits, only trouble (like wasting time for memory reallocation and having memory fragmented). If you need buffer, use static one (like pre-allocated array). -- Piotr Hellrayzer Dalek [EMAIL PROTECTED] -- Kliknij po wiecej! http://link.interia.pl/f18ed -- To unsubscribe or change your settings for TWSocket mailing list please goto http://www.elists.org/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be
