Cisco Network Slow in one segment

HI
We have some problems in production line with the download image process..
the network is configured with one cisco router 1800 ( 192.168.1.1 ) and next we connect a ppal switch catalyst 4506 ( 192.168.1.46 ) .. in this switch we have 2 vlans runing Vlan 1 (network 192 - office ) and Vlan 12 ( network 30-producction)
next we put a cisco Catalyst 6513 ( 30.0.1.22) and other catalyst 4506 ( 30.0.1.202) connect with fiber at the cisco catalyst 46..

The behavior of the catalyst 6513 its very faster for download but the other switch ( 30.0.1.202 ) its very slow .. how can we do for that this catalyst 4506 works better for download .. WE appreciate your support
Best Regards
