I have done benchmark tests with Evolution under the following conditions: (times measured since the reply button is clicked until the message is opened) 2.4.20-2.54 -> 9s 2.5.63-mm1 w/Deadline -> 34s 2.5.63-mm1 w/AS -> 33s The 2.4.20-2.54 is *not* a stock kernel, but Red Hat's own patched kernel (I think they include most of Alan Cox patches). Times are measured manually (don't know how to "time" the time elapsed since I click a button and the reply window is opened). Also, the filesystem is "ext2" running on a laptop (not a really fast hard disk). > How large are the dictionary files? Well, the aspell dictionary files are roughly 16MB for the Spanish dictionary and 4MB for the English one. -- ______________________________________________ http://www.linuxmail.org/ Now with e-mail forwarding for only US$5.95/yr Powered by Outblaze - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
