Easy questions about replication & Publication

Hi...
We have a SQL Server Std Edition that make syncronisation(merge
publication) with 100 mobile device.We create100 publications according to
our employees user id.We use articles with joins and user id for all
publications.The mobile devices make syncronisation over this publications.
Problem1:When I execute an insert or update statement in database , it cost
min 10 minutes for response.Last night I execute an update sql(for 10 rows)
at night.When i wake up morning,the transaction log is get full, and only 2
of the updates make succesfully.
Why database ddl operations get a long time to execute?
Problem2:How can I control transaction log automatically?
I'll wait for your answers..
Thanks...
