We ran a series of throughput tests using Chronicle Queue and Queue-Zero. Each test first appended 80M 500 byte messages, then read back all the messages (ie the reads and writes did not overlap). The appends and reads were all performed in a tight loop without any delay between iterations, and the time per 1M reads/writes measured through the duration of the test.
All tests were run on a Xeon E5-2650 v4 @ 2.20GHz, with queues backed by tmpfs. The test thread was pinned to an isolated core.
The results are summarised in the plots below for Queue and Queue-Zero separately showing:
– The time (in seconds) to append successive blocks of 1M messages
– The time (in seconds) to read successive blocks of 1M messages
followed by the same data plotted as throughput rates:
– The throughput (M msgs/s) when appending successive blocks of 1M messages
– The throughput (M msgs/s) when reading successive blocks of 1M messages
Each plot shows the results of the test with both Java and C++.
Queue – Times per 1M Appends and Reads
Queue – Message Rate per 1M Appends and Reads
Queue-Zero – Times per 1M Appends and Reads
Queue-Zero – Message Rate per 1M Appends and Reads
