[squid-users] strange reports after dl-malloc

Hi,
  The squid has been complied recently to use dl-malloc
after this i see no performance improvements, but the
General RUntime of Cachemgr show these readings.

Why is this showing absurd value. This was not the case till i used
dl-malloc.
My compile options were
Squid Cache: Version 2.5.STABLE7configure
options: --sysconfdir=/etc/squid --enable-storeio=diskd --enable-snmp --ena
ble-linux-netfilter --enable-underscores --enable-removal-policies=lru --dis
able-ident-lookups --with-dl --enable-err-languages=English --enable-dlmallo
c
This is on SUSE 8.0 WITH 2.4.18 SMP KERNEL
After all hard work still with 90-100 requests /sec squid hovers around 98%
CPU.
Any advice.
