You're bringing over 60 rows, but how many rows are in the table you are querying?

What version of Oracle?

Trying to bring over 60 rows with database link and write to table using CTAS. It is taking forever - going through Oracle - going through another Oracle that is hooked up with a gateway to Informix - yuck!! The waits are:

Event   Waits   Waits/sec       % total Wait Time (ms)  Wait Time/sec   % 
total        Average Wait     SQL*Net more data from dblink  1352 
80.8709175738725        99.1202346041056        14250   852.374685967221   
  0       0 

Any ideas how to speed up other than getting another gateway, creating ascii file and using direct load. Is there a way to tune related to Net8, database links?
Thanks,
Paula
