Load testing
DicomKit 1.0.0 under sustained load: storage, query and retrieve, DICOMweb, 1 GB images, a one-hour soak and the cost of the license check. Client and server ran on one PC over the loopback network, so the numbers show what DicomKit sustains on that hardware, not network limits.
On one 24-core PC DicomKit 1.0.0 received 40,000 images of mixed modalities without a single error (every image accounted for, sampled pixel checksums equal), answered up to about 7,223 C-FIND queries per second, retrieved studies by C-MOVE and C-GET at up to 32 at a time without errors, and served DICOMweb requests at up to 64 clients without errors. 1 GiB images were sent, stored, uploaded by STOW-RS with default options and read back intact; in the 1 GiB C-STORE steps memory stayed below 264 MB per process. A 90-minute soak with 6,844,887 operations had no errors and no memory growth; the server's OS handle count moves with thread-pool worker turnover in the .NET runtime, not with DicomKit objects. License checks cost about 3.2 ns per call.
| Scenario | Best throughput | p95 latency | Errors | Result |
|---|---|---|---|---|
|
LOAD-01 C-STORE throughput
All 40,000 images arrived and passed the checks. Throughput rose from 156 MB/s on one association to about 673-702 MB/s at 16-64 associations; at 64 associations the PC's CPU averaged only 52 %, while the slowest images (17 MB DX, 32 MB XA) waited up to 2.1 s, so that step was not limited by CPU; the server was also writing about 8 GB of files per step (its share was not measured separately).
|
702 MB/s 64 associations
|
106 ms | 0 | Pass |
|
LOAD-02 C-FIND, C-MOVE and C-GET
No errors in any step, including C-MOVE at 16 and 32 studies at a time (about 2,894 new associations to the destination). C-FIND peaked at about 7,223 queries/s, C-MOVE at 1,145 MB/s and C-GET at 9,229 MB/s; the 32-study C-MOVE and C-GET steps were limited by the PC's CPU.
|
9,229 MB/s C-GET, 32 studies at a time
|
48.9 ms | 0 | Pass |
|
LOAD-03 DICOMweb (QIDO-RS, WADO-RS, STOW-RS)
No errors at any step; most steps at 32-64 clients were limited by the PC's CPU. The FileSystemDicomWebStore that ships as a reference store keeps every instance's metadata in memory: after 96,772 instances the server held 3,003 MB of managed memory (about 32 KB per instance), so a large archive needs its own IDicomWebStore.
|
266 MB/s STOW-RS, 32 clients
|
18.4 ms | 0 | Pass |
|
LOAD-04 Large files (1 GiB images)
All large images arrived intact and memory stayed bounded with default settings: at most 174 MB working set in the sender and 264 MB in the receiver while 8 GiB were in flight. One association moved a 1 GiB image in about 4.9 s (208 MB/s); STOW-RS stored it with default options in 2.7 s and WADO-RS read it back at 444 MB/s.
|
500 MB/s C-STORE 1 GiB, 4 in parallel
|
8,196 ms | 0 | Pass |
|
LOAD-05 Mixed load: 1 GiB images during normal traffic
Nothing failed, but the small images slowed down while 1 GiB images were moving: throughput fell from 2,440 to 1,231 images/s, p99 latency rose from 13.94 ms to 38.56 ms and the slowest image took 2.9 s.
|
762 MB/s small images alone
|
10.6 ms | 0 | Pass |
|
LOAD-06 Soak test (90 minutes)
No memory growth: over the last 30 minutes the server working set changed by 8.12 MB/h and the client by 9.41 MB/h, and there were no errors. The server's OS handle count kept rising slowly (807 at the start, 1,458 after 90 minutes, 151 per hour over the last 30 minutes) and a full garbage collection did not lower it; a handle census showed the growth is in Event handles (+471 in 12 minutes with the full mix, +102 with DicomServer alone and no web server). It is not caused by opening associations (6,000 short associations left the count flat), and it is not a DicomKit leak: two heap dumps of a 40-minute DICOM-only soak, 30 minutes apart, show every DicomKit and socket object count unchanged, while the extra Event and Thread handles match thread-pool worker threads that had exited and were waiting for the .NET runtime's periodic dead-thread cleanup (+17 dead workers, +19 thread handles, +46 event handles); by the end of that run the count had come back down.
|
371 ops/s C-FIND over 90 min
|
2.85 ms | 0 | Pass |
|
LOAD-07 License-check overhead
EnsureLicensed takes about 3.2 ns per call; even for the cheapest guarded operation (opening a 9 KB file in memory, about 5.0 us) that is under 0.1 %.
|
0 | Pass |
Soak: 90 minutes at 16 concurrent clients, 6,844,887 operations, 0 errors; memory 580 MB at the start, 786 MB at the end.
Test PC: Intel(R) Core(TM) i9-14900K, 24 cores / 32 threads, 64 GB RAM, NVMe SSD, Microsoft Windows 11 Pro build 26200.9711, .NET 10.0.12 (one PC, client and server on loopback). Enterprise license. Run a20bedea-bacd-468b-af8d-945829c4b81f, source commit b804fb7.
