No.It doesn't.But many have a wrong idea that this tool improves booting time.Infact the Bootvis.exe tool is no longer available from Microsoft site.
The question comes what does this tool really do?
Bootvis.exe displays various time-interlocked graphs showing such things as CPU Usage, Disk I/O, Driver Delays and resume activity. Bootvis.exe can show many types of useful details; the best way to start is by dragging an area on the graph and either double-clicking it or right-clicking to use the context menu to see what options are available. The operating system instrumentation starts about one second after the boot loader loads. Overall boot time shown in Bootvis.exe should add BIOS power-on self test (POST) time + one second. Taking boot traces with Driver Delays will lengthen boot by two to three seconds. The resulting binary file will be several megabytes in size.
But remember Bootvis.exe is not a tool that will improve boot/resume performance for end users. On the other hand there are reports that Bootvis.exe cannot reduce or alter a system's boot or resume performance. The boot optimization routines invoked by Bootvis.exe are built into Windows XP. These routines run automatically at pre-determined times as part of the normal operation of the operating system.
Reference:-fast boot and fast resume
So What's the normal booting times?
According to Microsoft:-
The design goals for Windows XP on a typical consumer PC are:
•Boot to a useable state in a total of 30 seconds
•Resume from Hibernate (S4) in a total of 20 seconds
•Resume from Standby (S3) in a total of 5 seconds
Boot and resume times are measured from the time the power switch is pressed to being able to start a program from a desktop shortcut.
