In-Depth Information
YSlow has given my page an overall grade of C and you can see the individual scores for each of the
checks.
Figure 1-11.
Using YSlow against the page
Notice that we got an F for the “Compress components with gzip”. That is because we currently
have not configured the server to support compression. We can also see the individual files that
YSlow
suggests we should be compressing; it knows that these files are plain text files and therefore should
compress well to a much smaller size.
If you drill into the Components section of
YSlow
, as shown in Figure 1-12, you can see much more
detailed information about each component—in fact, more detail than we saw in Firebug earlier. This is
why I always use a combination of tools when examining websites, since there is no single tool that
shows everything.
