Hello, I recently plan to switch my 200 PC (W95 or DOS)+ 10 SUN workstations network to use Linux + Samba. It was previsouly using Netware 4.1 (not too bad) and Netware NFS (a nightmare !) My current configuration is made of 4 identical machines - bi-PII 300MHz + 128 Mo - 2*9 Go UW SCSI with soft raid level 1 - Linux 2.0.33 - Samba 1.9.18p7 Currently, this configuration is _really_ slower than the netware one with single processor computer. I read and did whatever is written in faq and docs regarding speed. But no big improvement. I'd like to keep this Linux+Samba configuration, but I really need speed. Any idea ? I also want to connect some DOS only client. I use MS client version 3.0. When I use the MS basic redirector, I cannot view or map any drive on the samba machines, unless I use 'security = share' which really not what I want as all the users have a unix account on which they identify, so I use 'security = user'. With the MS full redirector, it works fine even in user security mode, but it takes 90 k more memory under 1M, and I _really_ need that memory on my DOS only machines ! Thanks for help
