No, the Macintosh Carbon/GUI version and the CLI version are more or less 
the same speed except for DNS lookups (which are *way* faster in the CLI 
version). On x86 hardware, the Linux version is slightly faster than the 
windows version on the same machine, particularly at DNS lookups, but 
also slightly faster in general.

There are three issues that primarily determine speed. First is the total 
size of your log files. It doesn't matter so much how many files, only 
the total size really matters. Second is the number of sub-reports each 
log entry appears in, on average. If you filter out most log entries, so 
they don't appear in any sub-report, that will be much faster than ten 
sub-reports that all include all log entries. Third is the complexity of 
your configuration settings. Then more fields you have configured, and 
the more entries in each field, the slower Summary is. So, for example, 
if you have a list of 400 agents to filter Summary will be slower than if 
that field is blank.

Across platforms, the Linux version is the fastest and AMD processors are 
faster than Intel processors (of similar rated speeds). The Macintosh 
versions are faster per Mhz, but you can get x86 processors that have 
enough extra Mhz to more than make up for that (at least right now).
