Hi, I have a significant performance problem with busybox 1.18.3 modprobe.
Quick benchmark, 20 iterations of: "modprobe iptables -q"
Busybox: 1.15s
module-init-tools: 0.12s
This is hitting me in two areas, one is boot speed is slower than expected, but
more importantly it's crucified my iptables performance. Inexplicably iptables
(1.4.10)
calls modprobe something like 21 times each time it's run (makes firewall init
a multi-minute process)
Obviously fixing iptables is desirable, but is it possible to improve
performance
of busybox modprobe? Looking at strace the big difference seems to be the
read of the various files, busybox apparently using lots of getc()?
Any thoughts on a solution?
Thanks
Ed W
I have pasted the strace of the two modprobes below for completeness
