Re: New Laptop = VMware slower?! Nov 21, 2005 4:03 PM
I have been working with an Inspiron 6000 running Libranet Gnu/Linux(Debian 3.1 with some admin
tools and some other software added) and with kernel 2.6.14-2. I have made sure that I am in performance mode and have used gkrellm (compiled from latest source) and the gkfreq plugin to monitor the frequency. It is at 1600 mHz continuously and I have a 1.6 GHz Pentium M CPU. Also the real-time clock is rtc not genrtc. Currently I'm not concerned with poor time keeping in the W2K guest-later on that one. I am using Workstation 5.0 with a W2K guest at SP2. Boot and shutdown times are very slow. Also opening any application takes many seconds. I have my W2K desktop set to open apps with a single click. When I single click on an icon, nothing happens for many seconds but finally the selected application will open. Also the cursor is often missing in text dialogs, such as the login dialog, as well as sometimes in a command-prompt window. In the later the cursor comes and goes based on what has been done in the window. Run-time performance of my applications, at least those that do not write much to the screen, appears to be unaffected. However, I can type at the command line faster than the system can keep up. Even during login, typing the password has the asterisks one or two characters behind the key being struck. I have never seen this behavior before. Its like the refresh operations on the screen are orders of magnitude too slow. But compute intensive and even disk I/O intensive operations complete as I expect!? The really strange result is that I can speed the boot process to nearly what I have had on my previous laptop, an Inspiron 8100, by resizing the Vmware window continuously during the boot process. The same works for shutdown. Also when W2K is finally up, double clicking on an icon will bring the application up immediately. In fact the second click can be any place on the desktop(outside of another icon or command-prompt window). The other characteristic that is strange is that the task manager shows 100% CPU use on W2K even with the most minor operation. At the same time gkrellm shows essentially zero CPU on Linux. This occurs outside of CPU intensive applications. Examples, are opening and closing Explorer, loading Internet Explorer, etc. The mouse pointer shows the hourglass for a long time after the app is open. Sometimes just clicking on the desktop clears the hourglass! It seems to me that something is amiss with interupt handling or with the W2K graphics being starved for CPU cycles. I was using APCI and not APM. However, I have just recompiled the kernel using only APM and Vmware is back! The bootup and shutdown are like they should be, a single click on an icon brings up the app rapidly, etc. The CPU appears to be running at full speed always with no way of reducing it. The centrino cpu frequency scaling system appears to depend on APCI being present. Thus ScatterBrain and other posters with similar problems might want to try recompiling the kernel using APM and not APCI. Perhaps there is a kernel boot parameter that will fix the interupt handling with graphics that seems to be at the root of the problem. My BIOS is a bit out of date, at A07 and with A09 available. The A08 BIOS update mentioned some changes to the video BIOS, but I'm not sure that is related to the current problem. My video card is an ATI M22 (Radeon Mobility M300) according to lspci. This fix comes at the cost of some other functionality. Hopefully there is a fix via a boot parameter for the problem with APCI on this latptop. Delbert Franz |

I don't have performance problems with Ubuntu, but the dmesg-messages were familiar and there is a bug opened:
https://bugzilla.ubuntu.com/show_bug.cgi?id=17569 to quickly fix the issue, run "sudo /etc/init.d/hotkey-setup stop" |

Re: New Laptop = VMware slower?! Dec 9, 2005 10:32 AM
ScatterBrain,
I'm trying to figure out if we hve the same problem. Every two, three seconds or so, my WMware freezes for half a second. Not WMware itself, but the guest OS running in WMware. I have a Dell Latitude D810 with XP pro. The virtual machines I'm running are W2000 installations. I have tryed everything - resinstalling WMware, disabling speed stepping, disabling DVD and USB in the virtual machine. It would be interesting if we have the same problem, since you are running Linux and I'm running XP. |

Have any of you tried loading down the host OS slightly (e.g., "nice +10 ls -lR /")? I found this to help the guest performance for some reason on my Dell M50 (see yesterday's thread at http://www.vmware.com/community/thread.jspa?threadID=29012&tstart=40
I would be interested in hearing if you observe the same effect. Is this strictly a problem with the Dell laptops? |

kl1278 has posted another solution (setting max_cstate) in this thread http://www.vmware.com/community/thread.jspa?messageID=312185񌍹 it requires root access and setting the scaling governor to performance but it works better for me than the busy loop (the fan isn't constantly on now).

Have you read the link sent by jrj? The solution it provides is working well on an Inspiron 6000:
#!/bin/bash echo 1 > /sys/module/processor/parameters/max_cstate vmware echo 8 > /sys/module/processor/parameters/max_cstate |
