The hit rate is not stable #188

Closed GoogleCodeExporter closed 9 years ago

Hi, I'm using spymemcached 2.7.2, the server is membase1.6.5.4. 
OS is redhat.

When I use spymemcached2.7, the hit rate is always 1. 
After I upgrade to spymemcached2.7.2, the hit rate is always below 1.

URI base = new URI("http://localhost:8091/pools/");
ArrayList<URI> uriList = new ArrayList<URI>();
uriList.add(base);
MemcachedClient memcachedClient = new 
MemcachedClient(uriList,"default",null,null);

Then I start 100 threads, each thread will write 2000 times and read 8000 times 
for the same keyset. However, there are some keys's value is null after 
memcachedClient set the value.

Does someone have this issue?

Is it possible that your dataset changed.  Can you post a test that shows 
different hit rate between 2.7 and 2.7.1?

This may also be fixed by a get bulk issue, and it may just be that 2.7.1 is 
more correct.
