Instance CPU Utilization

Test 1. Bulk-edit 5 consecutive runs of 100K records, starting from 1VU up to 5VU. From the Instance CPU utilization graph, you can see that the bulk-edit process consists of 2 parts: file uploading(90-120 minutes) and records processing.
*During the Bul-edit for 4 VU, one process was uploading 100K records file for more than 4 hours( jobs finished processing about 21:30, and the grey graph was running up to 2 a.m), but on all others bulk-edits jobs there were no problems with this file.

Test 2.   Bulk-edit 100-1000-5000-10k records successively from 1VU up to 5VU

1. Item records update:
   1. Upload file with item barcodes 
   2. Click the Start bulk edit option in the Action menu and make the following changes:
      1. Set Temporary location to Clear field
      2. Set Permanent location to < to the value available on test environment>
      3. Set Status to Unknown
      4. Set Temporary loan type to Clear field
      5. Set Permanent loan type to < to the value available on test environment>
      6. Add Administrative note by adding text: "This is a new administrative note"
      7. Add Action note by adding text: "This is a new action note"
      8. Suppress from discovery (set the value to true)
   3. Confirm the changes
   4. Commit the changes
   5. Verify the changes are correct
   6. Download the file with updated records
   7. Download the file with errors (if applicable)

Test 1: From Was run manually from UI run Bulk-edit job with the configuration above. Run up to 5 concurrent processes in new browser tabs. Check if after the update files are downloaded successfully. 

Test 2: Manually tested 100k+50k+1 record files DI started simultaneously on every 3 tenants (9 jobs total).

Test 3: Run CICO on one tenant, DI jobs 3 tenants, including the one that runs CICO. Start the second job after the first one reaches 30%, and start another job on a third tenant after the first job reaches 60% completion. CICO: 20 users, DI file size: 25k

Test 4. To define the optimal value for RECORDS_PER_SPLIT_FILE(500, 1K, 2K, 5K) data-import job with PTF-Create-2 profile were run for 25K for 1 tenant simultaneously, for 2 tenants and for 3 tenants.. Was run from the Jmeter script. The configuration above was added to the POST method to run bulk-edit with proper configuration. Tests were run for 100-1000-5000-10k records successively from 1VU up to 5VU
