Hi, I'm just clueless with one particular behavior of the readlines function. I've written a sample program that illustrates this "prehaps bug" I'm encountering.
The box I used for this is an AMD Sempron 2800+ with 256 Mb of RAM : - When run on this standard etch box as a cgi script in apache2, it runs in less than a second. - When run in a vserver guest on this standard etch box from the commandline, it runs in less than a second. When run in a vserver guest on this standard etch box as a cgi script in apache2, it takes 7 seconds to complete! During this time, CPU usage is 100%. A friend of mine cannot reproduce on a Gentoo box with a similar setup. Updating vserver and the kernel to the latest version does not fix the problem. Using a brand new vserver (using newvserver and aptitude install apache2, with standard conffiles) does not fix the issue. I've narrowed the problem to the readlines() function. Questions arise from this : - can I narrow it better than readlines(), perhaps in C/C++ ? - is this apache2's or vserver's fault although similar perl or php programs (i.e. that read input) do not have the same problem? - any ideas, advices on all this? Thanks in advance, Alexandre
