Message-ID: MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org I am comparing 2.4.21-pre3-ac4 2.4.21-rc5-ac1 2.4.21-rc6-ac1 In the last two kernels, something is definitely not right. LaTeXing a big file takes about twice the time compared to the same job under 2.4.21-pre3-ac4. However, I am not totally satisfied with the 2.4.21-pre3-ac4, either. In the beginning just after a reboot, the condition is really nice. However, after a while, "time"ing a job reveals that something bad is happening in the first column of "real" time, which means the wall-clock timing. One might say that it is still better with 2.4.21-pre3-ac4 than the situation with 2.4.21-rc5-ac1 or with 2.4.21-rc6-ac1, because it still does not contaminate "user" time in the middle column. With 2.4.21-pre3-ac4, as everyone comlained, there seems to be a problem with the cursor movement while kernel-compilation in the back. The mouse movement seemed to have improved in 2.4.21-rc6-ac1. But overall performance hit is just not acceptable. BTW, the .config file for 2.4.21-rc6-ac1 has been taken from 2.4.21-pre3-ac4 during compilation. The motherboard is an Asus with the Nvidia2 chipset. Main system is running off SCSI hard disks under Adaptec U2-SCSI PCI controller. No ATAPI hard disk is running at the moment. I never used the installed ATAPI CDrom during the test. In the emaillist, I have been reading about random halts in recent kernels, i.e., 2.4.21-rc*. Well. I did not experience such a drastic things. maybe because I did not wait long enough. Regards, G.
