Neo4j query taking long time
I hope this helps . If you're trying to get a user's timeline, I would think you'd start with the specific user, then connect to other nodes via the relationships you're interested in. The current query isn't taking advantage of pattern matching or t

What causes this high variability in cycles for a simple tight loop with -O0 but not -O3, on a Cortex-A72?
wish of those help In recent Linux kernels the automatic NUMA page migration mechanism periodically shoots down TLB entries so that it can monitor NUMA locality. TLB reloads will slow down the O0 code, even if the data remains in the L1DCache.The pag

Why is my SSE assembly slower in release builds?
fixed the issue. Will look into that further You're timing in reference cycles with rdtsc, not core clock cycles. It's probably the same speed both times, in core clock cycles, but with the CPU running at different frequencies.Probably a debug build

From S3 to Snowflake and performance
To fix this issue Snowflake Has some documentation that should answer this pretty well here. In short: Ideally your files are big, but not so big and/or complicated that they take more than a minute to process.I have some snowpipes that handle a lot

Why these 2 similar queries in Snowflake have very different performance?
I wish did fix the issue. in the second query you can see bytes spilled to local storage is 272gb. This means that the work done in processing was too large to fit in the cluster memory and so had to spill to local attached SSD. From a performance pe
