Subject: [Bug 165814] New: very low (19 times) performance of widgets entry&label in comparison to GTK+-1.2
http://bugzilla.gnome.org/show_bug.cgi?id=165814 gtk+ | gtk | Ver: 2.6.x
Summary: very low (19 times) performance of widgets entry&label in comparison to GTK+-1.2 Product: gtk+ Version: 2.6.x Platform: Other OS/Version: Linux Status: UNCONFIRMED Severity: major Priority: Urgent Component: gtk AssignedTo: [EMAIL PROTECTED] ReportedBy: [EMAIL PROTECTED] CC: [EMAIL PROTECTED]
In the GTK+-2.0 (tested versions 2.4 and 2.6)
the widgets "entry" and "label" have very low performance (until 19 times) in
displaying text in comparison to GTK+-1.2.
The test loop consists of 4 calls of the procedure gtk_entry_set_text (4 distinct entry widgets) and 4 calls of the procedure gtk_label_set_text (4 distinct label widgets). The widgets are immediately updated by gtk_widget_draw(w,NULL); while (gtk_main_iteration_do(FALSE));
The results of "entry" and "label" performance tests: ------------------------- GTK|RH->RH|RH->SO|BC->SO| ------------------------- 1.2| 1 ms| 2 ms| 4 ms| 2.4| 3 ms| 38 ms| 24 ms| 2.6| 3 ms| 37 ms| 26 ms| ------------------------- (particular results attached below after the test source)
Column "GTK" - version of GTK+
column "RH->RH" - results OS: RedHat 9 linux, CPU: Pentium 4 2.8 GHz, DISPLAY
set to localhost:0
Column "RH->SO" - results OS: RedHat 9 linux, CPU: Pentium 4 2.8 GHz, DISPLAY
set to remotehost:0
Column "BC->SO" - results OS: BlueCat 5 linux, CPU: some x86, DISPLAY set to
remotehost:0
As remote host it's used Solaris 8 on Sun-Blade-100 (sparc). The time is measured in integer milliseconds. The antialiasing was disabled.
