Do any of you have a benchmark for measuring how fast a filesystem is
for plan 9?.
Read, writes, creates...
It doesnt take too much time to write one, but if anyone has already done it...
TIA.

Hello,
one of my hosts is rejecting cpu command.
term% cpu -h co
cpu: waiting for FS: Hangup: Hangup
term%
or more simply
term% cpu -h co
cpu: waiting for FS: :
term%
the host left message in /sys/log/cpu:
cpu: srvauth: can't establish ssl connection: no free devices
this message comes from srvp9auth(int fd, char *user) in cpu.c
/* set up encryption */
i = pushssl(fd, ealgs, fromserversecret, fromclientsecret, nil);
if(i < 0)
werrstr("can't establish ssl connection: %r");
pushssl() in /sys/src/libc/9sys/pushssl.c is
ctl = open("#D/ssl/clone", ORDWR);
if(ctl < 0)
return -1;
really
% cat '#D/ssl/clone'
cat: can't open #D/ssl/clone: no free devices
% ls '#D/ssl'|wc
129 129 1569
note #D/ssl include clone, therefore
% ls '#D/ssl'|grep -v clone|wc
128 128 1554
Questions
(1) 128 is the limit of #D/ssl/n ?
(2) why #D/ssl/n is not freed ?
(3) what happened with my host if it should be freed ? any suggestion
welcome.
(4) how to fix? rebooting is required ?
thanks in advance.

x40=; grep 128 /sys/src/9/*/devssl.c
Maxdstate= 128, /* must be a power of 2 */
> (2) why #D/ssl/n is not freed ?
maybe they are in use. grep /ssl/ /proc/*/fd | wc
> (3) what happened with my host if it should be freed ? any suggestion

kill the programs that are using them.
unless it's a kernel leak.
> (4) how to fix? rebooting is required ?
if it's really a kernel leak and not just programs
using them all, then yes you'll need to reboot.

lmbench, with some hacking, and APE, maybe.

I was thinking the same thing, but maybe with bonnie:
