Speed of capture- tethering

What factors play into how fast images are captured via tethering?
computer speed?
network speed (when capturing to a network drive)?
1394 6-pin vs 4-pin connection?

we would love to shoot tethered. However we can not make it through a full session without locking it all up. We shoot family and children. Especially with the children our rate of capture can be as quick as we here the beep. Sometimes it lags and will then load up 4 or 5 at a time in CPOne. However, inevitably it will get 8 or 10 behind in loading the images and won't load anymore. We'll have to disconnect the camera and reconnect it, then it will start working again, unfortunately we loose those shoots that didn't download. Especially with children, one of those could have been "the shot". Any ideas?
typically we shoot to a laptop with a 6pin-4pin cable. I have also tried a 6pin-6pin on my desktop. Have tried v4 and v5 (both of which are much better than the impossibility when we tried in v3).
Thanks.

  Because of your 4-pin firewire I was asking myself whether you are on Mac or Windows? There is no speed difference between 4- en 6-pin firewire. The 4-pins connection lags power. Do you use Canon 1D or 1Ds mkII?

  opps.. on windows machine, using a p30+ on a Mamyia 645AFDII.
  Laptop Specs - XP sp3, 2ghz processor with 2gb RAM. CPone v 4
  Desktop - XP SP3, DualCore 3.2ghz, 3.25 (4 installed)gb RAM,
  
  i knew the 4 pin lacked the power, was wondering if the lack of power decreased performance.
  
  please also note that i'm an idiot and just realized i posted under the Mac forum. Rather than me posting twice, can Admin please move this over. sorry and thanks.

  Looking at your setup I would first rule out the network by tethering to the local computer. Although I don't suspect the network to be the bottleneck, the combination of network and tethering does not excite me in the first place (it can work though). Both computer should do the trick specs wise, although the 2 GB RAM and 2 GHz processor of the laptop can become a limiting factor after a number of images to generate the previews in time. Check whether CO4 or 5 is the only application running while tethering to prevent other programs take away these resources.
  Firewire however, being it 4- or 6-pins to your P30+, is potentially the biggest bottleneck. Firewire speed with Windows is very much fluctuating depending on the hardware but I have rarely seen a good performance but mostly mediocre or bad. See if you can find a friend with a Mac (any Mac) to try (Firewire is good working on Mac).

  that makes a lot of since. I rarely ever use firewire because of it's instability on windows machines. i figure it was just the devices i was using, but if this is a known issue, it explains a lot.
  
  I tried tethering with saving the files on the local machine and not over the network. Still ran into the same issue.
  I think everything is pointing toward the firewrie.
  thanks again.
