Samba consumes a lot of resources

[Claude Marinier]

Hi,

I am testing on loriot: VMS 7.3, Samba 2.2.7a, and MultiNet V4.4 Rev A
on DEC 3000 Model 600 with 384 MB memory. After solving the "Flags =
UCX_SERVER" problem and the authentication problem, I am now actively
testing.

I am testing from MS Windows 2000 Pro with SP3. From Windows Explorer
through My Network Places / Entire Network / Microsoft Windows Network /
DREO / loriot, I went into the marinier share (from homes) and tried to
edit a file with GVIM (right click ans Send To). The system is sluggish
(slow to respond). Doing MONITOR SYSTEM produces.

	Node: LORIOT             17-JAN-2003 10:54:21
	Statistic: CURRENT       SYSTEM STATISTICS
	CPU Busy (79)
	Cur Top: SMBD_ANTIOCH-SP (11)
	Page Fault Rate (972)
	Cur Top: SMBD_ANTIOCH-SP (1)
	Free List Size (25497)
	Mod List Size (1587)
	Direct I/O Rate (247)
	Cur Top: SMBD_ANTIOCH-SP (23)
	Buffered I/O Rate (1856)
	Cur Top: SMBD_ANTIOCH-SP (859)

When I logged out from the PC and stopped the SMBD_ANTIOCH-SP process,
things settled down to a normal state (it took several seconds).

Generally, things are a bit slow, opening a directory (clicking the plus
sign) in particular; there is a noticeable delay when opening a file but
it is only a few seconds (3 or 4).

Notepad seems OK.

>From previous messages, it may be that we must be careful which Windows
applications we use to access files on the VMS system. It this true? Is
there a list of recommended applications?

Thanks.

; Template for VMS

; ============================================================================

;

; Things you need to check:

; --------------------------

;

; 1: Make sure that the user specified in "guest account" exists. Typically

;    this will be a user that cannot log in and has minimal privileges.

;    Often the "nobody" account doesn't work (very system dependant).

;

; 2: You should consider the "security =" option. See a full description

;    in the main documentation and the smb.conf(5) manual page

;

; 3: Look at the "hosts allow" option, unless you want everyone on the internet

;    to be able to access your files.
