["Christopher M. Penalver" <christopher.m.penalver@xxxxxxxxx>]

abeep, this bug was reported a while ago and there hasn't been any
activity in it recently. We were wondering if this is still an issue? If
so, could you please test for this with the latest development release
of Ubuntu? ISO images are available from http://cdimage.ubuntu.com
/daily-live/current/ .

If it remains an issue, could you please run the following command in
the development release from a Terminal
(Applications->Accessories->Terminal), as it will automatically gather
and attach updated debug information to this report:

apport-collect -p linux <replace-with-bug-number>

Also, could you please test the latest upstream kernel available following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Please do not test the daily folder, but the one all the way at the bottom. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested. For example:
kernel-fixed-upstream-v3.11-rc5

This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag:
needs-upstream-testing

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER

As well, please remove the tag:
needs-upstream-testing

Once testing of the upstream kernel is complete, please mark this bug's
Status as Confirmed. Please let us know your results. Thank you for your
understanding.

Title:
  Sluggish performance after 70% of memory is in use

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  I am using ubuntu 10.10 ( 2.6.36-020636-generic) on my lenovo-410 64-bit laptop, having 8gb of ram. the system works absolutely fine, the performance is good, but when the memory reaches to around 5gb then the system performance is sluggish, I know Its basically because of the paging of memory which is causing this,
  i had set cat /proc/sys/vm/swappiness to 0 . so i tried to disable swapping by setting swapoff, in this case it did not write paged memory to swap file but the result was even worse, i.e. when 5gb memory was used the system just got stuck, and the HDisk light was continuously blinking.
  So is there any setting which could resolve the issue and avoid paging, as my laptop has ample amount of RAM. It would be of great help if someone has solution for the same
