Hi,
One other quick check would be to see if you have any network errors showing up
in the output of 'ifconfig' on the client PC.
For tuning take a look at
https://cwiki.apache.org/confluence/display/GEODE/Network+Configuration+Best+Practices
There are a lot of possibilities there, but I would suggest focusing on
net.ipv4.tcp_rmem and net.ipv4.tcp_wmem and increase those to 32MB as suggested.

Hello User,
my question is network request is very slow ,only 5000/second ,
how can i fix it???
ths problem is my server is CentOS7 ,hardware : CPU 8700K ,
memory:32G , disk:intel 760p 256G , network : 1000M
and i start geode 1.4.0 , use gfsh command :
start locator --name=locator1 --port=30000 --bind-address=192.168.0.226
--http-service-port=0 --http-service-bind-address=192.168.0.226
--properties-file=./config/server.properties --J=-Dp2p.handshakeTimeoutMs=75000
configure pdx --disk-store
start server --name=server1 --server-port=0
--locators=192.168.0.226[30000] --bind-address=192.168.0.226
--J=-Dgemfire.ALLOW_PERSISTENT_TRANSACTIONS=true --force=1
--properties-file=./config/server.properties --groups=leap,lwfp,portal
--J=-Dp2p.handshakeTimeoutMs=75000
create region --name=r1 --type=REPLICATE
1)at the server pc , run java code , the region entry size is 0 ,
get region entry , speed is 63000/second
Properties props = new Properties();
ClientCacheFactory cf = new ClientCacheFactory(props);
ClientCache cache = cf.addPoolLocator("192.168.0.226",
30000).set("log-level", "WARN").create();
Region<String, String> region =
cache.<String, String>
createClientRegionFactory(ClientRegionShortcut.CACHING_PROXY).create("r1");
final AtomicInteger counter = new AtomicInteger(0);
final AtomicInteger idx = new AtomicInteger(0);
for (int i = 0; i < 1; i++)
{
new Thread(new Runnable()
{
public void run ()
{
while (true)
{
region.get(idx.getAndIncrement());
counter.incrementAndGet();
}
}
}).start();
}
2)but at the other pc , at same network , ip address
192.168.0.169 , same 1000M network , the same code , get region entry from the
192.168.0.226 server , speed is 5000/second
