I made two test , one with gdb5.1.1/host NT4/ remote target i386-elf and one with cygwin package gdb ( last one) /host w2k/remote target i386-elf..Remote target monitor is redboot. Result is the same as with Insight <--> the problem is on gdb : The download is very fast but debugging is slow.We also have made the trial with a Linux platform as host and then response time is OK <--> the problem is connected with window. Then we also have analysed the network traffic ( with ethreal) during the debugging session in both case. I t seems that when using host = window we have a delay due to the naggle algo of tcp level. This delay should be off when using little packet ( this occurs when debugging ). On the host=linux the delay is off. do you know this problem,? I also loocking for a work around ( just download over tcp and the debug over serial) I also shall contact the gdb mailing list because it seem to be a window-gdb problem Gilbert Keith Seitz schrieb: > On Thu, 2003-05-22 at 01:55, gilbert buob wrote: > > the response time is very very slow.
