1  Game Development / Networking & Multiplayer / C++ vs Java on: 2006-07-27 21:21:25
I have looked at the Online Casino/Gaming downloadable games, and most seem to be have written in C++ / MFC.
Is this because of:
- Download speed: Is this because of the smaller size of application for downloading (about 5 MB), compared to 20+ MB for a similar Java application.
- Speed of execution: I know that Java is certainly catching up in terms of speed.

Anything else?

2  Game Development / Performance Tuning / Best O.S. / Hard Drive Size for NIO Server load testing... on: 2006-06-03 21:38:58
I am currently load testing a NIO Server to see what would be the maximum number of Client connections that could reached, using the following PC: P4, 3GHz, 1GB RAM, Windows XP, SP2, 110 GB Hard Drive.

However, I would like to test the Server/Client performance on different OS's, e.g. Win Server 2000, Linux, Solaris.

Which would be the best possible option from the following:
1. Partition my current drive, (using e.g. Partition Magic), to e.g.
  - Win XP: 80 GB
  - Win Server 2000: 10 GB
  - Linux: 10 GB
  - Solaris: 5 GB
  - Shared/Data: 5 GB
2. Install a separate Hard drive with the different hard drives
3. Use a disk caddie, to swap in/out test hard drives.
4. Any thing else?

- Would the Operating System's hard drive size affect the Server/Client's performance, e.g. affecting the number of connections, number of File Handles, the virtual memory, etc.?
- Can anyone recommend an OS for Server testing?

Many Thanks,
Matt Wink
3  Game Development / Networking & Multiplayer / Re: SocketException: No buffer space available (maximum connections reached) on: 2006-05-30 17:29:51
The exeception occurs when "using a single client making multiple connection requests to the Server", i.e. a loop making connections to the Server one after another.

I've already seen this page, but thanks anyway.

Does any one else (blahblahblahh, Markus_Persson, etc.) have any experience of this problem?

4  Game Development / Networking & Multiplayer / SocketException: No buffer space available (maximum connections reached) on: 2006-05-29 20:16:53

I am currently doing some load testing of a NIO TCP/IP based Server:

- Server and Client on same machine.
- PC: P4, 3GHz, 1GB RAM, Windows XP, SP2

I seem to always reach a limit on the number of connections to the Server (not sending any messages), i.e. using a single client making multiple connection requests to the Server.
After a few 1000 connections (Task Manager: 130k Handles), I get the following exception:
... ....
at ....
Caused by: No buffer space available (maximum connections reached?): connect
at Method)

I have tried the following, (with little or no success):
- Changing some of the registry settings, e.g. TCPNumConnections, MaxUserPort. (No effect)
- Using Heap buffers (No effect)
- Using the compiler options (CPU usage went from 100% to 75%): -Xmn 100M -Xms -500M -Xmx 500M

Will using a non-NIO Client help?

Is this problem Win XP O.S. specific. Does Win XP place a limit on the number of:
- Simultaneous TCP connections
- File Handles/Descriptors
- Socket buffer size

If the problem is O.S. related:
- Can any of the above parameters be changed, e.g. Registry settings
- What would the best OS for a Server, e.g. Windows Server 2000/2003, or Linux (which version: Redhat, Fedora, Debian)?

Does PC's processor speed/RAM have any effect, i.e. will 300MHz, 128 MB be as good as 1GHz, 1GB RAM?
Many Thanks,
Matt     Smiley

Many Thanks for the info.

6  Game Development / Networking & Multiplayer / Web Hosting on: 2006-03-25 12:22:46

I am interested in setting up a Java game server for a Massively Multiplayer Online Game (MMOG).

Does anyone know of or could recommend a UK Web Hosting company that offers:
- Game server hosting for MMOG's?
- Co-location or shared/dedicated servers onto which Java software could be installed?
- Support for MySQL/SQL Server databases?
- Fail over (and recovery) of servers?
- Regular backups of data?
