In 1.85.1.oc-1, figure out why loading a record is so slow (see email on 6/24)

[MartijnR]

use old pyxform-transformed XForm

http://localhost:8005/single/fs/i/SdiVErEP?ecid=1

1. run empty form
2. log full record after loading to console and add date to first question
3. temporarily hardcode that record into enketo-webform-fieldsumission.js as instanceStr

in 1.85.1.oc-1:

• loading empty form takes 7 seconds and loading record takes 20 seconds

form initialization:

• with record: 20 seconds (so all of it)

form initialization profiling results with record:

• model init: 173.136962890625ms
• preloads init: 0.68505859375ms
• first calc update: 7250.473876953125ms 👈
• langs init: 0.14697265625ms
• pages init: 4.166259765625ms
• itemset update: 0.360107421875ms
• set all vals: 17.3046875ms
• relevant update: 3382.621826171875ms 👈
• second calc update: 7199.59033203125ms 👈
• required update: 1717.180908203125ms 👈
• mask: 0.714111328125ms

profiling results without record:

• model init: 47.880126953125ms
• preloads init: 0.68994140625ms
• first calc update: 2915.235107421875ms

• second calc update: 2850.10107421875ms
• required update: 717.287109375ms
• mask: 0.701171875ms

Number of calcs performed with record in first and second update each: 83 (probably includes nested) Number of calcs performed without a record in first and second update each: 83 (probably includes nested)

Limitations:

• It's possible that the server-to-client requests in the OC system take long (which is not taking into account with my testing).
• I used a dummy external data file. A very large file could make a difference.

I do not understand the slowness when loading a record.

• [x] confirm again that latest Enketo Express OC does not get slower when loading a record. - No it's the same as with 1.85.1.oc-1 (20 seconds) but in the latest master it doesn't matter whether a record is loaded or an empty form. It's the same.

• [ ] set up a way to test this in enketo core, using an OLD version of enketo-core: 5.13.1, and set validateContinuously to true at http://localhost:8005/?xform=ScreeningLabs.xml, add comment-status function
