[Bug 236275] Re: System very slow after suspend-to-ram
I have this issue too on a Thinkpad X200. I had Maverick 64-bit installed from Oct-2010 without issue, but I did a fresh install the other day and have been having the issue ever since. Both were 64-bit Maverick. Using current kernel (Linux x200 2.6.35-28-generic #49-Ubuntu SMP). Contrary to others, no swap is being used and only an average 800 MB of RAM is being used (I have 4 GB total) when this happens. Initially I thought it had to do with CPU frequency scaling, but forcing the cores to run at max speed doesn't change anything. Also, when the issue is not occurring and I force the CPU cores to run at min speed (800 MHz), it's still much faster than when in this post-suspend slow state. top shows nothing out of the ordinary - no run-away processes or the like. Nothing noteworthy in syslog. But the cores are completely maxed out at the smallest effort - running gmail in Firefox for example.

I have the same problem.

[Bug 236275] Re: System very slow after suspend-to-ram
I had been getting the problem in previous versions of ubuntu on this Macbook 4.1. I was still getting them as of recently on Lucid. I followed a link from a launchpad bug report page (https://bugs.edge.launchpad.net/ubuntu/+source/linux/+bug/400413) to a kernel bug tracker report page (https://bugzilla.kernel.org/show_bug.cgi?id=14718) and saw the suggestion to try booting with the kernel option 'irqpolled' enabled. So, I tried adding an entry for 2.6.32-24-generic with irqpoll enabled in grub.cfg, and since booting with that option, I haven't been having problems with sluggishness after suspend. But I wonder, why does changing the hardware interrupt type to polling fix the issue? ** Bug watch added: Linux Kernel Bug Tracker #14718 http://bugzilla.kernel.org/show_bug.cgi?id=14718 -- System very slow after suspend-to-ram https://bugs.launchpad.net/bugs/236275 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Hi, I have absolutely the same problem on my Dell laptop with Ubuntu 8.10, 64-bit (2.26.27-11) I used the same test to check the speed - encoding media file with lame. The slowdown is about 4 times. The good news is that I think I found why! (at least on 2 Dell laptops). The problem is in AC Adapter. When I use one with lower voltage then standard one. Here is how I reproduce this: 1. Start the system with standard (for my laptop) adapter - 90W. The system is fast. 2. Close the lid to suspend. 3. Change the adapter to 65W (you can do it with Dell, that is ok, just charge time is much longer) 4. Open the lid to return from suspend. 5. Now the system ~4x slower. 6. UNPLUG the 65W adapter to run on the battery power - and it is FAST again!! Plug 65W adapter back - and it is slow. I did few times - and it is definitely about adapter. Now the interesting thing about this that if I do full restart with 65W adapter - everything works fine! This quite annoying cause at work place we have lower voltage adapters and we need to restart OS every morning. Hope this will help to fix this bug.

I can quantify the slowdown of the system after a suspend-to-RAM. I am not sure if the same result applies for a suspend-to-disk. Steps to reproduce: 1. Boot up computer 2. Run a sample program and time it. 3. Suspend to RAM 4. Wake up. 5. Run the same sample program and time it. Time taken will be about 3x more.
