- Contact Atmire to ask how we can buy more credits for future development
|
||||
- I researched the Solr `filterCache` size and I found out that the formula for calculating the potential memory use of **each entry** in the cache is:
|
||||
|
||||
```
|
||||
((maxDoc/8) + 128) * (size_defined_in_solrconfig.xml)
|
||||
```
|
||||
|
||||
- Which means that, for our statistics core with *149 million* documents, each entry in our `filterCache` would use 8.9 GB!
|
||||
|
||||
```
|
||||
((149374568/8) + 128) * 512 = 9560037888 bytes (8.9 GB)
|
||||
```
|
||||
|
||||
- So I think we can forget about tuning this for now!

|
||||
- I see that there was a nice optimization to the ImageMagick PDF CMYK detection in the upstream `dspace-5_x` branch: [DS-3664](https://github.com/DSpace/DSpace/pull/2204)
|
||||
- The fix will go into DSpace 5.10, and we are currently on DSpace 5.8 but I think I'll cherry-pick that fix into our `5_x-prod` branch:
|
||||
- 4e8c7b578bdbe26ead07e36055de6896bbf02f83: ImageMagick: Only execute "identify" on first page
|
||||
- I think it would also be nice to cherry-pick the fixes for [DS-3883](https://github.com/DSpace/DSpace/pull/2020), which is related to optimizing the XMLUI item display of items with many bitstreams
|
||||
- a0ea20bd1821720b111e2873b08e03ce2bf93307: DS-3883: Don't loop through original bitstreams if only displaying thumbnails
|
||||
- 8d81e825dee62c2aa9d403a505e4a4d798964e8d: DS-3883: If only including thumbnails, only load the main item thumbnail.
