In Q2 2021, we released an enhancement to the ACC queue that supports configuration of the interval that the ACC checks the server for available resources. This was to optimize load balancing for volumes of short runtime agents. Below are the tests we ran and performance we measured.
In these tests, we used 300 agents that fetch data from News sites. Of those 300 agents, 228 agents use HTML Parser, 4 agents use JSON Parser, and the remaining 68 agents use both Dynamic Browser and HTML Parser. All 300 agents are configured to use the Exit If Data Exist command which supports download of deltas only. In this way, agents run very quickly (often within a few seconds) since they run a frequent check for new content but only occasionally detect new content for download.
The following table shows the list of servers and their specs that have been used for performance tests.
| Server Type | vcpus | RAM/GiB memory | SE Version |
|---|---|---|---|
| Bare Metal Server | 24 Cores Logical Processor 48 Intel (R) Xeon(R) CPU E5-2687W v4 @3.00 GHz | 256 GB RAM | 2.74.3 |
| Azure Windows VM (Standard F16s_v2) | 16 vcpus | 32 GiB memory | 2.74.3 |
| Azure Windows VM (Standard F32s_v2) | 32 vcpus | 64 GiB memory | 2.74.3 |
ACC Setup
| ACC Thresholds | Session Delay |
|---|---|
| sessions:40, cpu:90%, mem:90% | Default Blank |
SE Server Setup
Follow the Windows Heap Setting Tuning article to change the Windows Server Heap Settings.
| SE Server Heap Settings | SE Version |
|---|---|
| Windows SharedSection=1024,20480,4096 | 2.74.3 |
Agent Settings
| Internal Database | Exit If Data Exist | Data Validation | Export Target | Session Support |
|---|---|---|---|---|
| SQLite | Yes(Internal DB) | Yes | JSON and AWS S3 Export | Single |
Several groups of tests were done on 3 different types of servers using the same 300 agents and SQLite as an internal database, to check the ACC Queue performance and SE performance.
