Command window response slowness

[stevec]

Like the program, but a couple of gripes/enhancement request
(1) the "slowness" of the windows, e.g. in a Command window, if I use the mouse wheel to scroll up/down, it's very easy to "overload" the window, i.e. if I do a lot of up/downing, it fills the buffer
(2) the Break key (Shift+Esc) is very slow to respond, and actually stop the query

How many lines of text are in the buffer when this happens? I have also noticed that for very long output lines (> 1000 characters), the Command Window will slow down.

(2) the Break key (Shift+Esc) is very slow to respond, and actually stop the query

Not all operations can immediately be cancelled. For example, when the Oracle Server is waiting for a lock or is performing an internal sort, it is not listening to your break requests.

Marco,

(1) just checked, only 262
- PC is WinXP Pro, 512Mb, 1.2 GHz, so not new, but hardly old

(2) why can I stop it immediately in a SQL*Plus window ?

Cheers,
Steve C.

That should perform just fine. Is there anything specific I need to do to reproduce this slowness? Or is it always slow?

(2) why can I stop it immediately in a SQL*Plus window ?

Good question. Are you perhaps using "Single Session Mode" (Tools > Preferences > Options tab page)? If so, does it help if you switch to "Dual Session Mode", restart PL/SQL Developer, and try again?

(1) it's always slow when the text size increases

(2) checked option and it's set to Multi session
- do I change it to Dual ?
