Does the window has any tool to measure the actual<br>
network throughput of the 1GHz ? Or do you have any<br>
H/W tool to measure it ? If so, how many Mega bytes/sec<br>
of throughput ?<br>
<br>
Can the window run remote client ?<br>

I did not change any EDM applications or EPICS base. The protocol<br>

BSP. It </span></font><font face="Times New Roman" color="black"

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