When attempting to test the latest build (r4280) running from Linux server to Linux client, I am seeing very poor performance, about half of what I can achieve with 1.0.1 using identical settings. It appears to be an issue with Xvnc, because replacing Xvnc with Xvnc 1.0.1 brings it back to normal. Switching out VNCViewer doesn't seen to matter. I also tried it without the patch I checked in recently to improve JPEG performance (r4259), and no effect. Also tried increasing the JPEG compression buffer (no effect.) Also verified that both ends of the connection are using SIMD extensions.
An unrelated issue is that whenever I try to use the vncviewer GUI to set the Zlib level to something other than the default, the server crashes (the log says "ZlibOutStream: deflate failed".)
