Hi,
I think the first problem is the sheer number of requests you're making
each time the user zooms in (exacerbated by use of Control Flow).
1) You should use a scale-threshold on the javascript side too so it
doesn't bother making requests for layers that are out of zoom.
2) Your GWC seems to be working fine, at least for MasterMap.
3) I'd recommend merging the three layers (250k, ODC, Streetview) into a
single layer group within geoserver; this would obviate point 1 entirely.
4) Use OS Miniscale rather than Strategi for the further-out zoom levels.
Similarly VMD between strategi and Streetview. Meridian and VML are also
useful.
5) Your WMS requests are tiled. Do they need to be? I understand doing this
for more complex datasets, but for simpler ones you're adding the overhead
of many many requests contrasting to one request for a larger image which
will take slightly longer to render but should be a saving overall.
That all said, beyond the above issues, your stuff seems to render fine.
Cheers,
Jonathan
