Slow System Performance
Posted: Thu Dec 22, 2011 11:24 am
Hi,
I am having performance issues with my Dell Latitude E6520 laptop. I believe that I have identified the performance bottleneck to be the Seagate ST320LT014-9YK142 HDD. However I have been unable to resolve the problem.
Here are the additional specifications of the laptop:
CPU: Core i7 2620M (2C/4T)
Memory: 4GB DDR 1333
GPU: Integrated GPU + nVIDIA NVS 4200M
OS: Windows 7 Enterprise 32-bit
I believe that the HDD is the issue because whenever I am running multiple processes which access the disk simultaneously, the paging activity goes to 100% (I found this by monitoring the LogicalDisk:% Disk Read Time event using Perfmon) and when this happens, the whole system slows down to a snail's pace. I find this behavior somewhat puzzling because when I look at the memory utilization in Task Manager, it only shows 1.7 GB as being used and I still have almost 1 GB of free memory. In other words, why should there be so much paging when I have so much free memory?
I ensured that the HDD is accessed using UDMA 6 and not PIO.
I have Windows 7 set to automatically manage the paging file size for all drives - it has set the page file size to be 2984 MB.
Can anyone help?
Thanks.
