[Samba] Slow Samba Printer initialisation, status, and printing

[Michael Carmody]

OK, I have been wrestling with this for two weeks now, so somebody please 
help !

We have an existing Samba Print Server, running RedHat linux, kernel 
2.2.19, that runs fine, but is a P133 with 64 mb ram. So we built a new PC, 
the slowest thing we could buy, a duron 1 ghz with 512 mb RAM. Old printer 
server is running Samba 2.2.5,  new printer server is running samba 2.2.5, 
and Slackware 8.1, kernel 2.4.18. Both are using lprng as print spooler. 
Old is currently a WINS server, the new is pointing  at the old smb WINS Server

File browsing and creation is quick, easy and no problems. Printing takes 
nearly 30 seconds to open, and another 10 seconds to initialise, and the 
print jobs take forever to come up. It is functional, but very slow. The 
new print server runs rapidly with no problems, printing/initialisation and 
file browsing. In the machine specific logs I get the following error 
message repeated two or three times before it does actually connect:

[2002/09/02 16:16:16, 0] 
rpc_client/cli_spoolss_notify.c:spoolss_connect_to_client(79)
   connect_to_client: Can't resolve address for PC194-70

There is nothing in the smbd or nmbd logs, they remain empty, except for 
server restarts, and then this error message appears in the nmbd log:

[2002/09/02 16:11:35, 0] 
nmbd/nmbd_responserecordsdb.c:find_response_record(235)
   find_response_record: response packet id 31803 received with no matching 
record.

But this only shows when server is started.

The initial browse to host and open also takes a fair while (~10secs), are 
these delays normal ? Is there something I've configure wrong ?
Any all help appreciated.

checkpc produces no errors, and lprng directly from the server to the 
printers takes neglible time (less than 3 secs to printer receiving data).
