Thanks, that was really helpful. Now I'm trying to interpret the results :-)
What operations does the "Blit" time include (i.e. what is actually being timed)? On the server side blitting seems to be the limiting factor, but on the client the blit time is often close to zero. I don't really understand this, but I'm assuming that server side and client side blitting are different operations. Similarly, exactly is the "Recv" time reporting? Thanks for any insight you can provide. cheers - jc On May 20, 2010, at 10:59 AM, DRC wrote: > Not using TurboVNC 0.6, but I added a TVNC_PROFILE environment > variable > to the next release of TurboVNC which will spit out similar types of > metrics when you are running the Unix server or client.
