First Time Memory Use Observations using 2.4(.7) Kernel - 20010804
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
Hello,
After a few hoops and loops of efforts over past week I have managed to to have my SuSE 6.4 start up the 2.4 kernel. I wanted to get a feel for the 2.4 kernel and specifically the memory management behaviour. I had felt there were some issues at least at the 2.2 Kernel, but not sure how much is kernel vs application related.
My first experience is with the 2.4.7 Kernel. I have not used a 2.4 kernel before. I am not using a varient of the kernel with the single-use patch from Daniel Phillips.
My initial overall impression of the 2.4.7 kernel is encouraging. On the specific memory management aspect, I saw some positive improvement in the way memory is "consumed", but discovered by accident that in another manner a sudden leak from 182MB to 230MB+. When I checked via qps to see where the gain was, I could not seem to find any cause for this jump in the applications. as it had seemed to be indiacted via qps with a 2.2 kernel. I can only assume the cause of this sudden bump was within the Kernel itself, but cannot prove that. This type of bump up in memory never happened with the 2.2 Kernels I have used to date, and I have been using the 2.2.19 kernel almost since its release. I shut down the one major application I had been using to see if it would restore memory to pre-application like usage levels. Sadly it only partly did and not to level I am accustomed to with the 2.2 kernels.
I am not on the Kernel mailing list, so any thoughts to my observations or how I can validate my observations with metrics would be appreciated be replying to my eMail address. I am not using a varient of the kernel with the single-use patch from Daniel Phillips.
