[mapserver-users] Best way to store ArcInfo annotations in PostGIS?

[Daniel Morissette]

Martin,

Only some benchmarks could tell us for sure, but I don't imagine that
option 1 would be that much slower than option 2, if it's slower at all.
Once the text has been stroked in option 2, you cannot change its style
or size any more. OTOH, with #1 you keep all that flexibility.
Personally I'd go with #1 unless you can verify with some tests that #2
is really faster, and if that's the case we'd like to hear back from you
and find out more.
