3 Definitions 3 See details here: Performance is property of a software system which indicates its ability to be as powerful, fast, stable, and scalable as required. Ramp-up test (also known as capacity test): Virtual users are steadily incremented until performance saturation occurs (adding more virtual users results in response time growth rather than growth of transactions processed per second or in system failure). The goal of test is to find point of system saturation and describe it: how many transactions/sec, network traffic/sec, etc. Ramp-up test reveals how powerful system is. Short low-, mid-, and high-load tests: Test is running with fixed number of virtual users for a specific period of time to measure response times under different load conditions determined from the ramp-up test. These tests are contingent on results of ramp-up test because “low”, “mid”, and “high” levels of load are relative to the level of saturation. High load is usually deemed to be 80% of the saturation load. These tests show how fast system is. Longevity test (also known as soak test or stability test): Very long high load test to test system stability. Longevity test shows how stable system is. Rush-hour test: Rapid increase of number of users logging onto the system (imitating start of business day) followed by rapid user logout imitating activity at the end of business hours on the low-load background. In case of tight project schedule this test can be replaced with login storm test. This test shows how stable system is. Scalability tests: Series of ramp-up tests conducted against various system configurations (different number of application servers, different number of CPU cores, etc.) Scalability tests show how scalable system is, i.e. how its capacity changes with increase in power of resources provided.

18 Response Times 18 Data for Medium Load  Average of average response time decreased from 0.6 to 0.4 seconds  Primarily this is due to the not reproduced issues with -side Search cache which was met in March RR testing  and News response times are better now as well

24 May RR Expectation List 24 ApplicationWhat we expect implements new caching for equity views, so we expect that performance improves, especially for these views. We expect "HTTP Status-Code=500 (Authorization failed:..." issue (836) to be fixed to prevent failures with users logins especially in rush-hour. Moving servers to Win2008. We expect that performance is at least the same as it was before. implements new caching for Equity views, so we expect that performance of these requests improves. Memory leak is expected to be fixed Traffic volume will not affect performance since issue with network is claimed to be fixed (1567) If is upgraded to, we expect performance improvement. Also, >> migration should make it possible to test with wider universe of instruments ( ) which now causes to crash
