Does the camera come with it's own display ? Or do you use EPICS CA for<br>
display ? If <span class="520173119-10102007">the real data
throughput to the EPICS display is 334 Mbits/sec,<br>
you should see 42 Mega Bytes/sec of high traffic using the Window
network<br>
perfromace monitor. If it shows no traffic at all, then the display
could be<br>
only 1 frame/second (e.g. 11 Mbits/sec) while the data transfer is 334
Mbits/sec.<br>
<br>
What's the protocol the camera use for tranferring the data to the host
PC ?<br>
I thought it's the GigE network. If so, you should see at least 334
Mbits/sec<br>
data throughput on the window network performance monitor. Something<br>
does not make sense to me.<br>

Does the window has any tool to measure the actual<br>

H/W tool to measure it ? If so, how many Mega bytes/sec<br>

Yes, in the 100MHz NIC, the actual network throughput is not <br>
30Hzx1024x768x8 bits. But it is greater than 10Hz. Thus, the system

not have to run in a private network.</span></font><font

Perhaps I will have the optimization written in a publication, so that<br>
hopefully it can help the Linux or vxWorks users. If so, will you<br>
feedback to this list regarding how much improvement you achieved<br>
in the Linux driver ?<br>
