newbie question about polygraph

Hello,
i'm testing my own proxy against polygraph simple.pg simulation. But there
are some aspects that i don't understand after reading the User manual at
http://www.web-polygraph.org/docs/reference/output/console.html .

*(1) (2) (3) (4) (5) (6) (7) (8) (9)*
000.09| i-dflt 23 4.52 196 0.00 0 1
000.17| i-dflt 48 5.00 199 0.00 0 1
000.25| i-dflt 73 5.00 199 0.00 0 1
000.34| i-dflt 98 5.00 198 0.00 0 1
000.42| i-dflt 125 5.40 185 0.00 0 1

The above output is copied from
http://www.web-polygraph.org/docs/reference/output/console.html. On that
page it is said that column 4 is "number of replies recieved so far (across
all phases)". Right Now i'm experiencing this column value is very similar
between a polyclt console and polysrv console, but polysrv 5th column
(request rate) is much lower than polyclt. BTW i edited simple.pg with this
line : "recurrence = 1% / SimpleContent.cachable;", so the 7th column (hit
rate) on polyclt is always close to zero.

My question is, what does this mean ? shouldn't it be that, if the 4th
column on polysrv is similar to polyclt, then the 5th column should too ?
Does this means my proxy overloaded ?

Also, i occasionaly get "connection closed before sending header" error on
polyclt, does this means that when polyclt is trying to send a request to
the proxy across a persistent connection, the proxy closed the connection ?
Or does it means something else ? Also (just wondering) is this kind of
error only comes up at client console ? could it also appear on server
console ?

regards,

sam
