News Stream Server: Bottleneck command queue

[sebschlicht]

Problem description

One requirement to the server due to the usage of Graphity is thread-safety.
Therefore all server requests are added to a shared thread-safe queue handled by a separate worker thread.
If this queue runs full response times will be very high.

Possible solution

Commands added to the queue should contain critical graph operations only, so that at least read requests can be handled parallel.

for the write optimized graphity version we can actually omit the command queue. this will be interesting to see
