Dear guys,
I have a qmail-ldap server that running well, except for its speed.
When a client sends a message (a simple one with text only), it will
take about 8 seconds for the email to disappear from the Outbox (I
mean, the time needed for email to get sent).
I tried to raise the number of users into 23, and sent email in the
same time (a couple times). The average time needed to send those
emails raised to 16, 25, 50 seconds. It even took over 1 minute for
some users. The receivers were local and remote (e.g., gmail.com).
Currently we're running a qmail server (qmailrocks installation), and
the time we need to send and email is only about 1 - 2 seconds (the
time it needs to process emails was even faster than the qmail-ldap
server). Was the location of the LDAP server has caused this? Below
is the architecture of our network. Both the qmail server and
qmail-ldap server were in the same network (DMZ), the LDAP server was
in the local network (LAN). *SW = core switch
LAN -------------|-----|SW|--------- FIREWALL/ROUTER

qmail-ldap server qmail-server
Is there a way to tune qmail-ldap server so it can work (at least) as
fast as the existing qmail server? I really need help due to this
problem and I will appreciate every single clue. Thank you in advance.
Regards,
sato
PS. I have a couple server that utilize the LDAP server :
1. Samba PDC for windows domain, about 300 users
2. Samba Winbind for squid proxy authentication, 150 users
3. Samba file server that heavily used, 300 users
