Re: [twsocket] TWSocket Buffer
You should upgrade your C++ Builder 6 to C++ Builder XE. Actually I have currently on my system c++ builder 6 + ICS ver 5 . also having many license of third party component for c++ buider6. Also My lot of project working on that . If I change the version of c++ builder 6 then lot of problem occurs in compiling and linking , upgrading the components . So I want to stick with that version . Thats why I need c++builder 6 + ICS ver 6 I understand. This is a classical situation. One in which no one should ever fall into... This is not sustainable on the long term. The more you wait to upgrade the more difficult it will be to upgrade. And one day, nothing will work anymore. when using third party components, you should only use/buy components with full source code and make sure you are able to rebuild the component (never use the prebuilt version, always rebuild everything yourself). This way, you'll be able to move forward as new compiler versions are out, even if the component editor stop making the components you are using. Upgrading component from one compiler version to the next is usually very easy. The more versions you skip, the more difficult it is to port the code to newer version. Here you have 10 years (or so, I don't remember when BCB6 was released) behind you. It will require some work to upgrade but in my opinion you MUST do it, or plan to retire soon...

Re: [twsocket] TWSocket Buffer
Hi, Thanks for help , I will definitly switch to latest versions of both c++ builder and ICS with 2- 4 months . But presently I need urgent help for compression of data and send to socket . Actually I have frequently In memory data (buffer) that I am continuesly sending to the clients . now I want to compress that In memory data(buffer) and than send to client . In previous post some one tell me that ICS version having this features using zlib (FTP/web server applicatons). but I could not find the any code snap in ICS version 6 for compression the buffer . so please help me this with some code snap or better if I got some sample .because I presetly stick with ICS ver 5 and my application is working smoother.

Re: [twsocket] TWSocket Buffer
In previous post some one tell me that ICS version having this features using zlib (FTP/web server applicatons). but I could not find the any code snap in ICS version 6 for compression the buffer . Zlib was available in ICS v5. Look at icszlibhigh.pas. Function ZlibCompressStreamEx compresses a TStream, which could be a TMemoryStream. This is used in FtpCli.pas. There are numerous other zlib functions available, including compressing memory buffers, which are widely documented on the web since zlib is C.

Re: [twsocket] TWSocket Buffer
ICSv6 is the same as v7 in using single window per many sockets. For v5, you may hit the limit for maximum number of Window handles per proxess with a few thousand sockets. With v7, we have been able to test up to 60k sockets. It could improve further but as Francois said the 2GB RAM limit for 32-bit processes is the problem. It will be removed when Embarcadero releases 64-bit compiler.

Re: [twsocket] TWSocket Buffer
Ok Thanks for valuable info . Can you tell me is there any method in ICS to compress the data and send to socket Both the ICS FTP and HTTP server include options to compress data sent to clients, but this is done at application layer, not socket layer. You would need to look at the source code and adapt it for your server, it uses ZLIB. Obviously you need to compress in a way that is compatible with the client software. Beware compression is CPU intensive, and compressing 1,000 streams at the same time will slow down your server significantly.

Re: [twsocket] TWSocket Buffer
I want to read buffer from files then compress after that send to client . Is that model possible Sure it is. As Angus said, compression is a CPU intensive task, so you'd better have multicore CPU and use multithreading to use multicore. If you have one thousand concurrent user doing compression, then you need a really, really large server. This is not bacause of ICS of course, just because of compression which is a CPU intensive task. Just to have an idea, let's have a batch file zipping a large file (so that it takes, let's say 30 on your computer). Then run a few hundreds simultaneous of your batches.

I guess you are using UDP not TCP. no I am using TCP There is no limit on the size of the data you can send at a time with TWSocket in a TCP session. But if you are looking at the network using a sniffer, you'll see the maximum packet size of your Ethernet network (1460 bytes). This doesn't mean your applicatyion data will be transfered whatever the size is. This doesn't depends on ICS, this is how a socket is working and how an Ethernet and IP network is working. Don't worry about packet size ! I have 3gb ram Not that much for a huge number of connections.
