Azure web app is a bit slow

[rmdocherty]

Have made some progress on speeding up service, but it is still slower than expected. Featurising is similar time, as is encoding (if done seperately). Segmenting is way slower than on my PC (1 min server vs 15s PC). I feel like this is a multithreading issue: are the first processes using up all the thread allocations because of my multithreading code? Is that even possible?

Possible solution: allocate less threads to each function s.t the first one doesn't get them all.

Fairly certain it's a memory problem (small files segment v fast on server). Two solutions: pay for more expensive plan again to get more RAM and/or follow #3 to have fixed memory constraints.

Having changed backed to subsample and testing a deploy, still seems to be slower than local. Having watched the memory on the VM, doesn't seem to be OOM but not much memFree (even if memAvailable is high). Bumping up to p2v3 a very tempting option.

Performance difference between p2v3 and p2v2 not super large. No real way to speed up unless we host our own and take advantage of #31.
