Some reports suggest that Google is working on PartitionAlloc-everywhere for Google Chrome. This will improve the performance of the browser and enhance the user experience.
The PartitonAlloc-everywhere will improve startup time, faster browsing, and improved RAM management for Google Chrome. This feature is currently available to beta users on Android and Windows. Google is also planning it for Linux users but currently, they are facing some issues.
“Switch to PartitionAlloc on Linux. This is already the default on Windows and Android and has been shipping to the beta on both platforms. Nevertheless, issues may remain on Linux,” a statement from Google engineer on Chromium bug post.
They are running some experiments where they found that merging regular and aligned partition could reduce memory usage and improve performance.
“Having two separate partitions is required when the regular one doesn’t provide the desired alignment. Without that, it’s beneficial performance and memory-wise to have a single partition. Performance is better since aligned allocations (which are actually plentiful in Chromium) can leverage the thread cache. Memory footprint improves from lower fragmentation, and not paying the fixed cost of partition metadata,” company's statement.
In addition to Windows 10 and Linux, Google is also testing ”PartitionAlloc-Everywhere’ for Android. According to Google experiments, this is a win for memory, performance, and stability, with the exception of the median GPU process footprint, which regresses by a small amount.
