After migrating from RHPAM 7.7.0 to RHPAM 7.10.0 we observed that opening assets takes much longer on the new version, >1 minute compared to several seconds on the older version.
Thread dumps show that threads are in the following execution path for some time:

The last line in this thread dump points to a code change that happened in 7.9 due to RHPAM-2865.
We need to make sure that opening assets in 7.10.0 has the same performance as in before that fix.
