Pavel Pereslegin updated IGNITE-17407:
--------------------------------------
Description:
The snapshot rate limit does not work correctly when set to values greater
than 100 MB per second.
Currently, the snapshot transfer rate is limited by the BasicRateLimiter.
Testing shows that limiter is unable to give more than ~119 millions permits
per second.
{code:java}
long dataSize = U.GB;
BasicRateLimiter limiter = new BasicRateLimiter(dataSize / 2);
int blockSize =
IgniteSnapshotManager.SNAPSHOT_LIMITED_TRANSFER_BLOCK_SIZE_BYTES;
long start = System.currentTimeMillis();
for (long i = 0; i < dataSize; i+=blockSize)
limiter.acquire(blockSize);
long totalSec =
TimeUnit.MILLISECONDS.toSeconds(System.currentTimeMillis() - start);
System.out.println("Speed= " + (dataSize / totalSec));
{code}
