Optimize PermissionChecker performance && adjust jsonrpc configuration #13034

skabashnyuk · 2019-04-01T12:51:44Z

What does this PR do?

It's an attempt to reduce the time needed to execute a single json-rpc call.
To test that I was using a scenario that is emulating Che6 workspace startup. It has 10 times more minor events aka logs in comparison to major aka statuses.

Figure 1:

this is how che server behaves without changes

what we can see here is

we can see the degradation of major queue. The size of this queue is very big. In this pr, I've changed an upper limit to reduce pressure on the heap.
The maximum duration of json/rpc call between 20-40 and it's started degrading after the point when heap was consumed almost completely.

Figure 2:

this is how che server behaves with queue adjustmens and query cache

what we can see here is :

performance of minor queue increased 8 times, major - ~12 times.
maximum time of message execution reduced about 10 times in avg.
a big part of the heap was consumed by http sessions (TODO create an issue here)

Figure 3

The number of rows fetched with and without query cache.

Time of execution with caching enabled from 13-53 -> 14-57
Time of execution without caching from 15-09 -> 15-13

what we can see here is :
If we are speaking about the test without caching - it's about ten's of millions of rows.
If we are speaking about the test with caching - it's about hundreds of rows.
it's important to constantly monitor DB statistic [Metrics] Database metrics #13223
