Since the server generating the large log files is running Apache, have you done
anything to decrease log file size? Such as:

SetEnvIfNoCase Request_URI
"\.(gif)|(png)|(css)|(js)|(ico)|(jpg)|(pl)|(cgi)|(rdx)|(cgi)$" nolog
CustomLog d:/logs/creation.log combined env=!nolog

There may be many other types of files you don't need. Let Apache clean up the
files rather than Webalizer. This might help a bit.

For future reference you may want to consider a 'fork' of Webalizer by Stone
Steps: http://www.stonesteps.ca/projects/webalizer/

Performance:

Stone Steps Webalizer running with a minimum set of group/hide filters, enabled
GeoIP and disabled DNS resolver on a 3GHz Core 2 ™ Quad with 4GB of RAM can
process 122161 log records per second. Adding dozens of filters, using robot
processing and user agent name mangling will reduce processing speed to about
80000 records per second on the same system.
