And "2-3 MB of RAM" isn't going to get you very far either: 2-3 GB would
help a lot more.

Have you installed the FLEX-1500 patch kit and done Step 5 in the
Troubleshooting guide?

That helps with CPU utilization.
Also on notebooks manufactured these days, they all seem to use the USB bus for
peripheral and hardware interfacing. Having multiple low speed devices or high
speed devices that continuously use the USB controller, like disk drives, are a
detriment to the performance of the FLEX-1500. Use this KB article to
determine if your FLEX-1500 is sharing a controller with other stuff.

As for your Atom machine, 1 GB or RAM is too little for Win7 Starter Edition, IMHO; add another 1
GB to get to the 2 GB max. The "Starter" version of Win7 is "crippled" by
default to work on low-end hardware You need a minimum of 2-3 MB of RAM for the regular versions of
Win7 x86 to perform optimally. RAM is cheap. Get lots of it.
Also with laptops and to a lesser degree desktops, you need to make sure that
you are not having excessive I/O latency from long duration DPCs

Anything that spikes above 1000 us is not good. If you see spikes above 3000
ms, this is bad for real-time audio applications like PowerSDR.

just got Flex 1500 and installed PSDR 2.0.16.
runs well on desktop: intel quad core 2.4 Ghz, 6 GB, Win7 HP runs marginally
on laptop: Pentium dual core 1.6 Ghz, 2GB, Win7 HP,
high to very high cpu utilization
receives but doesn't transmit on netbook: atom N450, 1.63 GHz, 1 GB,
Win7 starter
do I simply not have enough processing power and memory on the laptop and
netbook? is there anything to do short of more powerful computers?
