Hai Yes, 

first upgrade your samba version. ( http://www.enterprisesamba.com/old/samba-3/ ) 
add the sernet samba repo for ubuntu precise and upgrade to version 3.6.19 
and test again. 

If copy for example a large file to the share and what is the speed your seeing? ( in windows ) 
when done, 

apply this. ( read http://www.speedguide.net/faq_in_q.php?qid=247 ) 
netsh interface tcp set global autotuning=disabled
( this is the default : netsh interface tcp set global autotuningl=normal ) 
and test again. 

SolidWorks also have a history of locking problems, can you post your smb.conf.
Im not the locking expert, but maybe someone else knows, if your using wrong settings. 

wat does the performance test say :  
( Start > All Programs > SolidWorks ???? > SolidWorks Tools > SolidWorks Performance Test and SolidWorks Rx utilities. )
Have you disabled all the useless Win7 "bling" ?
Do you have the Aero theme enabled?

There are more settings to improve the network speed on windows 7, just google for it. 

And read this http://www.3dcadworld.com/why-solid-edge-matters-part-2/ 
and tell your suppliers that they should go support linux, and that 
you?re considering migrating away from SolidWorks, because of this bad support.

Good luck.
