I have a Question. If I start "bitcoin-cli getmempoolinfo" on my BitcoinUnlimited node, I get "size": 11386, but Blockchair.com is counting 1915 mempool tx only. Why the difference? Any ideas?
there is no right or wrong. if a tx happens not to make it to the mempool of the node that happens to mine the block, it will show up in the next block.
