If you turn on verbose gc for the JVM you could at least rule out GC pauses.
Hmm, exactly how do you route the requests through the apache server? It
almost sounds like your applikation is restarted every now and then, iirc
Apache only servers a limited amount of requests per server thread.

GC would be the first suspect, but then it could also be combined with a
swap issue, or a JVM bug.

Is there a limited number of models?
The model should stay decoupled from the state as they are totally distinct
so general-fn[model old-state] - new-state
then either you (if you know the model) or the user if they can choose any
model should define a partial fn
partial specific-model-fn
The same tip can be used in vim-fireplace with c!! (minus the quotes).
I find it especially useful when creating tests (as in OP).

Use the jvisualvm tool that comes with the jdk- you should be able to
connect to the clojure process.
Looking at the memory usage graphs, and if the heap size is banging against
the max heap size, then you might just be using too small a heap size - try
upping it.

Now, if took at most two args, this would be a sensible

Well first I'd say that the Java api you're calling into isn't very good if
it expects specifically java.util.HashMap. Clojure's map data structures
implement java.util.Map so generally they can be passed into Java api
methods that take the interface (good practice).
However, HashMap has a

I don't have any experience configuring Clojure apps on the JVM, yet, but
it may be that increasing the RAM on the server does not increase the RAM
allocated to the JVM instance Clojure is running on.

You are right. As you pointed out, my java interface design is not good.

Hi Yang,
'\0x09' is the same with '\t' , they get the same byte value 9. '\0x09'

By the way nginx-clojure won't do any converting about this case it just
