Description Michael Scharf

The current terminal implementation is about 60 times slower than for example rxvt (on cygwin) to show 3 MB of terminal input (http://artscene.textfiles.com/vt100/ to get all: http://artscene.textfiles.com/archives/vt100.zip). Here some performance numbers:

rxvt (on cygwin)     :      5.7 sec  550 kb/sec
hyperterminal        :     11.8 sec  265 kb/sec
xterm (on cygwin)    :     24.5 sec  127 kb/sec
sshview              :     40.3 sec   77 kb/sec

terminal (in eclipse):    333.8 sec    10 kb/sec

Remarks:

- rxvt is a vt102 emulator -- it's supposed to be a xterm replacement: http://sourceforge.net/projects/rxvt

- microsofts hyperterminal does not show anything at that speed. It shows the "result" at the end.

- sshview is a swing based eclipse ssh based terminal emulator: http://sourceforge.net/projects/parsec/

This bug is for improvements on terminal read.
See also bug 170814 for improving performance of terminal write.

I guess this can be declared fixed as per TM 2.0.1RC2 ?
Michael can you add some information how much faster the Terminal has become, and other interesting stuff for adopters?

According to hearsay, terminal has become up to 1000 times faster on Windows.
Does anybody have any concrete measurement?
