I'm going to comment on this because it sounds similar to a recent experience of my own. As illogical as it sounds I'm passing it on.  Recently I installed a samba server as a member server on an NT4 Samba/Ldap Domain. During this process I consolidated multiple servers into this one new member server. As soon one of these legacy systems was removed from the domain, file access became increasingly slow,right click operations on even local file systems annoyed and frustrated large number of users. You said the key word "old server" and I am taking a stab in the dark on this but if that server does not have the same netbios name ,legacy file and drive mappings on the client side crippled even the fastest of systems on my network. If this is the case and you still have access to your old server you just might want to test it by exposing your old shares as read only and determining if that helps log on speed.
In this particular case this is not a Samba issue so much as a Windows workstation registry and shell extension problem. I hope this provides some help. Good Luck.
