David,
Thanks for the example.
I got
OntModel:
[500] Bindings (batches of 50): 668
[25000] Query all: 437
[500] Naive: 422
[500] Union (no batching): 179
[500] Filter (batches of 50): 57
and changing to a default Model:
[500] Bindings (batches of 50): 351
[25000] Query all: 209
[500] Naive: 460
[500] Union (no batching): 192
[500] Filter (batches of 50): 70
The OntModel results were more variable, the plain default model results
were more stable.
IN is optimized (not sure which versions ...)
BINDINGs are (lightly) optimized - it (nowadays) tries to turn them into
a sequence of more grounded queries but that optimization wasn't in
earlier version of ARQ with BINDINGS.
qparse --print=opt --query=Q.rq will print out what the high-level
optimizer is doing.

Excellent, will get a copy of the latest ARQ and try again...

Thanks David.
(tried to attach the source file, but Gmail won't
cooperate for some reason, so it's included below in message body).
I have a feeling apache strips out attachments, so probably safer this way.
Here's the output on my machine with current (working ;-) ARQ:
[500] Bindings (batches of 50): 471
[25000] Query all: 1077
[500] Naive: 859
[500] Union (no batching): 338
[500] Filter (batches of 50): 228
I also hacked a no-batch version of bindings:
[500] Bindings (batches of 50): 481
[500] Bindings: 165
[25000] Query all: 947
[500] Naive: 998
[500] Union (no batching): 322
[500] Filter (batches of 50): 212
