swap can slowdown linux in certain conditions …
I realized the cause of progressive slowdown over time in Linux, specially for developer of designer machines can be due to utilization of swap space. I loaded over 4.3 million records in memory which necessiated the use of swap space. Unfortunately even after the program was completed, the swap space was not releasd and was used for other programs also even though sufficient memory was available.
So one a memory intensive program is run, it is likely to slow down your subsequent program due to swap usage. I think it is an implementation bug but haven’t checked enough to confirm / reject the theory.
Have you noticed this?
