Performance issue with tag |

Hello,
I have a performance issue with the tag operation.
Few repository stats:
Top level directories (modules) ~ 2900
Version controlled files ~ 65000
Repository size ~ 14.3 GB
Tags (lines in CVSROOT/val-tags) ~ 133000
Repository is on AIX 5.3 using CVS 1.12.13. It is uses exclusively
through pserver.
The tag operation on a single module, of < 100 files, takes between 15
seconds and a few minutes. When the command takes a long time the
lock CVSROOT/#cvs.val-tags.lock can be seen. Example output from a
longer run:
address@hidden w]$ date; cvs -d
':pserver:@cvs.example.com:2401/opt/cvs/prod_dept' rtag dummy_tag
mfleetwo_test; date
Thu Aug 7 16:19:48 BST 2008
cvs rtag: Tagging mfleetwo_test
cvs rtag: Tagging mfleetwo_test/DBDXML
cvs rtag: [15:20:08] waiting for cvsprod's lock in /opt/cvs/prod_dept/CVSROOT
cvs rtag: [15:20:38] waiting for cvsprod's lock in /opt/cvs/prod_dept/CVSROOT
cvs rtag: [15:21:08] obtained lock in /opt/cvs/prod_dept/CVSROOT
cvs rtag: Tagging mfleetwo_test/REPORTS
cvs rtag: Tagging mfleetwo_test/SDL

All other cvs operations only take a second or two. Can anybody
suggest anything to improve tag performance to a similar level?
Thanks,
Mike
