So, here's a quick and dirty bench, using both syntaxes on the Test pages:

[@
[[#default]]
(:if ! equal {=$Group} {<$Group}:)

:[[{=$Group}/]] /:
(:if:)
: :[[{=$Group}/{=$Name}]]
[[#defaultend]]
@]

(:pagelist group=Test fmt=#default:)

gives:

00.00 00.00 config start
00.00 00.00 config end
00.08 00.07 MarkupToHTML begin
00.09 00.08 FPLTemplate begin
00.09 00.08 MakePageList pre
00.09 00.08 PageListSources begin
00.10 00.09 PageStore::ls begin wiki.d/{$FullName}
00.18 00.12 PageStore::ls merge wiki.d/{$FullName}
00.22 00.15 PageStore::ls end wiki.d/{$FullName}
00.22 00.16 PageStore::ls begin $FarmD/wikilib.d/{$FullName}
00.23 00.16 PageStore::ls merge $FarmD/wikilib.d/{$FullName}
00.23 00.16 PageStore::ls end $FarmD/wikilib.d/{$FullName}
00.23 00.16 PageListSources end count=681
00.23 00.16 PageListSort pre ret=4 order=name
00.23 00.16 MakePageList items count=681, filters=
00.24 00.17 MakePageList post count=681, readc=0
00.24 00.17 PageListSort begin
00.28 00.22 PageListSort end
00.28 00.22 MakePageList end
00.59 00.49 MarkupToHTML begin
03.37 02.39 MarkupToHTML end
03.37 02.39 FPLTemplate end
03.38 02.39 MarkupToHTML end
03.40 02.41 MarkupToHTML begin
03.43 02.44 ReadApprovedUrls Site.ApprovedUrls begin
03.43 02.44 ReadApprovedUrls Site.ApprovedUrls end
03.45 02.46 MarkupToHTML end
03.46 02.46 MarkupToHTML begin
03.47 02.48 MarkupToHTML end
03.48 02.49 now

whereas:

[@
[[#default]]
(:template first {=$Group}:)

:[[{=$Group}/]] /:
(:template each:)
: :[[{=$Group}/{=$Name}]]
[[#defaultend]]
@]

(:pagelist group=Test fmt=#default:)

results in:

00.00 00.00 config start
00.00 00.00 config end
00.09 00.08 MarkupToHTML begin
00.11 00.10 FPLTemplate begin
00.11 00.10 MakePageList pre
00.11 00.10 PageListSources begin
00.11 00.10 PageStore::ls begin wiki.d/{$FullName}
00.21 00.13 PageStore::ls merge wiki.d/{$FullName}
00.25 00.17 PageStore::ls end wiki.d/{$FullName}
00.26 00.17 PageStore::ls begin $FarmD/wikilib.d/{$FullName}
00.26 00.17 PageStore::ls merge $FarmD/wikilib.d/{$FullName}
00.26 00.17 PageStore::ls end $FarmD/wikilib.d/{$FullName}
00.26 00.17 PageListSources end count=681
00.26 00.17 PageListSort pre ret=4 order=name
00.26 00.17 MakePageList items count=681, filters=
00.28 00.19 MakePageList post count=681, readc=0
00.28 00.19 PageListSort begin
00.32 00.23 PageListSort end
00.32 00.23 MakePageList end
00.57 00.45 MarkupToHTML begin
02.43 02.11 MarkupToHTML end
02.43 02.11 FPLTemplate end
02.44 02.12 MarkupToHTML end
02.46 02.13 MarkupToHTML begin
02.48 02.16 ReadApprovedUrls Site.ApprovedUrls begin
02.49 02.16 ReadApprovedUrls Site.ApprovedUrls end
02.51 02.19 MarkupToHTML end
02.51 02.19 MarkupToHTML begin
02.52 02.20 MarkupToHTML end
02.54 02.21 now

which is quite better!

It's time to update Site.PageListTemplates, no?
