      There's a reoccurring issue from customers (WT-15538) where application threads are blocked from doing work due to update eviction trigger threshold being met BF-40074 . A common work around to this issue is to increase the setting for the update trigger threshold. We can set the update threshold to the 20% default rather than 10% of cache to help allevite this problem.

      There's also on-going work to improve how application threads do eviction SPM-4369
