sockets - Linux Kernel parameters which can be tuned when TCP backlog exceeds in WebSphere MQ server -

-

we facing issue see tcp backlogs gets exceeded default value (100) on our mq server (v7.5) running on linux (redhat) platform during high number of connection requests on mq server. listenerbacklog configured 100 in qm.ini default listener backlog value (maximum connection requests) linux. whenever have connections burst , tcp backlogs exceeds queue manager stops functioning , resumes when queue manager/server restarted.

so looking whether there attributes in linux kernel related socket tuning can improve tcp backlog @ network layer , cause no harm queue manager.does increasing these values below in /etc/sysctl.conf resolve issue or improve performance of queue manager?

net.ipv4.tcp_max_syn_backlog = 4096

net.core.somaxconn = 1024

net.core.rmem_max = 16777216

net.core.wmem_max = 16777216

i have similar problem described in how prevent numbers being changed exponential form in python matplotlib figure : i don't want (in special case) weird scientific formatting of axis. problem different have problem @ z -axis. 2-d plots can use ax.get_yaxis().get_major_formatter().set_useoffset(false) . , there no function ax.get_zaxis() what use format z -axis same way? edit: example: from mpl_toolkits.mplot3d import axes3d import numpy np import sys import matplotlib import matplotlib.pyplot pyplot def func(xi, ti): res = 10e3 + np.cos(ti) * np.sin(xi) return res if __name__ == '__main__': timespacing = 20 timestart = 0 timeend = 1 time = np.linspace(timestart, timeend, timespacing) widthspacing = 50 widthstart = 0 widthend = 3 width = np.linspace(widthstart, widthend, widthspacing) reslist = [] matplotlib.rcparams['legend.fontsize'] = 10 fig = pyplot.figure() ax = fig.gca(projection = '3d...

php - Best Light server (Linux + Web server + Database) for Raspberry Pi -

-
i install web server database on raspberry pi (little computer). computer has 1gb ram. i want know best combination: linux distribution , web server , dbms run local server multiple users minimal latency, use php on server. , best settings performance , not have bugs (memory usage, disable plugin, disable service, etc)? i thought light debian , lighttpd server , sqlite database. solution? i think lighttpd + sqlite great choice. linux distro, debian @ centos or tiny core linux , although i'm not sure of compatibility pi. obviously, can't go wrong raspbian if want use in production , more stable performance, few more pi's , set them in cluster .
