I think you are trying to limit the wrong things. A limit on the number of windows won't help much, since load is not proportional to the number of windows. You are better off focusing on other areas. I would suggest the following areas; I'm sure others on the list have things to add. 1. CPU power 2. Server memory 3. Network bandwidth. 4. Disk to CPU bandwidth. Are you using IDE or SCSI disks? Start with "cat /proc/loadavg"; the first number is the average number of processes waiting to run. If this number is greater than the number of CPUs in your server, you need more processing power. EG: if you have 2 CPUs and this number is 3, you need more CPU. If that's OK, check your memory with "cat /proc/meminfo". This file will tell you a lot about your memory usage. Ignore MemFree; look at Buffers instead. If this number is low, you may need more RAM. Also look at SwapFree; if this is low, you need more swap space. Are you using 10 Mbit or 100 Mbit ethernet? Are you using switches or hubs? If the Collision light comes on more than once a minute, your network bandwidth is the problem and you try to use switches instead of hubs. Switches segregate traffic; if you use both hubs and switches, try to lay them out so that traffic is as segregated as possible.
