I still can't upgrade to 2.6, this box has a beta redhat 6.9.5 heavily tweaked and I can't seem to find the time to upgrade to 2.6 (the glibc threads upgrade scares me), if you can make a patch to 2.4 I will try it.* Jorge Nerin <firstname.lastname@example.org> wrote:Hello, I was testing the value of "2" in /proc/sys/net/tux/compression when I found that:Feb 24 15:17:56 head kernel: deflate in loop returned -5 Feb 24 15:17:56 head kernel: kernel BUG at gzip.c:3334!i've uploaded a new Tux patch to: redhat.com/~mingo/TUX-patches/tux3-2.6.3-B2 i've fixed all bugs in the gzip code i could find: made it use the 2.6 kernel's deflate library, and fixed a couple of bad assumptions. Memory consumption should be lower as well, since now deflate state is per-Tux-thread, not per-request. I've added the gzip fix from Miles Elam as well. i've done light testing with compression=2, but YMMV - does it work for you? i suspect the compression level should be configurable as well. Right now it's hardcoded to level 6 - what level would be the best? (this patch includes some more fixes as well - eg. stack footprint reduction for CGIs.). Ingo
About the compression level, the easy answer is to make it a configurable value, either at compile time, or better like a proc entry, but I find that 6 is a good answer, althougth the cvs folks always recomends 3.
